This review explores the potential of MXenes, a novel class of two-dimensional (2D) materials, in advancing energy storage and conservation technologies. MXenes exhibit exceptional physicochemical properties, including a high specific surface area (~390 m² g⁻¹ for MXene@PPy-800), outstanding electrical conductivity, and robust chemical stability, m...
Article
The introduction of harmful substances into water systems leads to water pollution. Pollutants can include microorganisms, chemical additives, or plastics. Currently, the increase in plastic production accounts for 80% of waste in the world's oceans. Microplastics differ in color and density depending on the type of polymer and are categorized as p...
Article
Full-text available
The article is dedicated to the study of MXene synthesis processes and their application as electrodes for supercapacitors. MXenes are two-dimensional nanomaterials with unique electrochemical properties, such as high conductivity and large surface area. The structure and physicochemical properties of the synthesized MXenes were investigated using...
Article
Full-text available
In the context of increasing industrial pollution and insufficient efficiency of traditional wastewater treatment methods, the issue of finding environmentally friendly and effective sorbents is particularly acute. Industrial dyes entering reservoirs change their color, are toxic and can pose a serious threat to human health and the ecosystem. The...
Article
Full-text available
The article provides an overview of modern methods of processing mining and metallurgical waste to obtain functional materials such as silicon, rare earth metals, nanoporous silica and other valuable components. The technologies of processing and purification, including hydrometallurgical and pyrometallurgical processes, as well as their applicabil...
Chapter
This chapter discusses current practices and new developments in the preparation of activated carbons for the adsorption of pollutants. There is widespread pollution such as pharmaceuticals and heavy metals in global surface water that needs to be mitigated and carbon sorbents made for it can be part of the solution. Preparing carbons for such chal...

This work describes the production of nanocellulose by removing lignin from biomass by the peroxide method in the presence of an H2SO4 catalyst and the study of its physicochemical properties. The structure of cellulose and modified nanocellulose was studied using Raman spectroscopy, IR (infrared) spectroscopy, X-ray diffraction, and SEM (scanning...
Article
Full-text available
An important technological solution to the problem of plastic pollution is to replace traditional non-biodegradable polymers, which are the cause of environmental pollution, with biodegradable polymer materials with physical and mechanical properties. Searching for ways to reduce the biodegradation of self-degrading biopolymers and waste and reduci...
Article
Full-text available
In this study, the synthesis of a new composite adsorbent using rice biosourced silica, silver nanoparticles and triethoxysilane as the raw materials for removal aqueous mercury ions from water is presented. The new composite material was synthesised by modification of the surface of rice husk based silica with silane groups and farther decoration...
Article
Full-text available
The article shows how the rice husk, which is the final waste of rice processing production, can be obtained from silicon dioxide of various degrees of yield, processed under different temperature conditions. As a rule, such waste is incinerated or can be simply thrown out. the smoke emitted from the incineration of such waste can negatively affect...
Article
Full-text available
The ubiquitous presence of microplastics in freshwater ecosystems has become a serious environmental problem with far-reaching consequences for both aquatic life and human well-being. This comprehensive review examines the multifaceted problem of microplastic pollution in freshwater, delving into its diverse sources, transport mechanisms, environme...
Article
Full-text available
Maximizing energy conversion efficiency is a major goal in the field of sustainable energy systems. In recent years, MXenes, a new class of two-dimensional materials, have attracted much attention in the context of improving energy conversion efficiency. This literature review provides an overview of the current state of energy research on MXenes,...
Article
Full-text available
An important technological solution for plastic pollution is the replacement of traditional biodegradable polymers, biodegradable polymer materials with physico-mechanical properties that cause environmental pollution. An urgent problem is the search for ways to reduce the self-decomposition of biopolymers and waste, as well as to reduce the cost o...
Chapter
Rice, which provides a major source of food for billions of people, covers 1% of the surface of the earth. Rice husk (RH), the outer covering of paddy rice, is an important byproduct during the milling process, and residue ash is generated after the burning of RH that is called rice husk ash (RHA), which is a primary waste material in the agricultu...

Full-text available
The generation of coal fly ash (CFA) in coal-fired power plants worldwide has been a major concern over the past few decades. CFA as a by-product possesses unique properties and chemical composition that could be utilized in resolving mercury contamination issues in Central Asia, particularly in Kazakhstan. This review gives an overview of coal gen...

Rice husks (RHs) are the hard-protecting coverings of grains of rice. Considering the fact that this agricultural waste accumulates over the years, the need for prompt resolve for RH waste is readily apparent. As claimed by the Food and Agriculture Organization of the United Nations (FAO), the production of the global paddy rice in 2016 is consider...
