The rapid advancement of perovskite solar cells (PSCs) marks a significant breakthrough in affordable photovoltaic technology with simple fabrication process and excellent performance. The remarkable intrinsic properties of perovskite materials, coupled with continuous optimization of key functional layers such as the hole transporting layer (HTL),...
Titanium dioxide (TiO2) is gaining popularity as a potential contender for photocatalytic carbon dioxide (CO2) reduction to transform industrial CO2 gas into fuels. It is also associated with the storage of inconsistent and sustainable energy of solar in the form of chemical bonds to close the carbon cycle. Nevertheless, pure TiO2 has a high band g...
Respiratory humidity sensors are essential for monitoring breath conditions in a variety of applications such as respiratory disease diagnosis, sleep apnea screening, and personalized medicine. With the increasing prevalence of respiratory diseases, such as asthma, chronic obstructive pulmonary disease (COPD), and sleep apnea, they have become esse...
Hydrogen as a clean fuel is increasingly sought after for its potential to replace non-renewable energy sources, with the hydrogen evolution reaction (HER) presenting a sustainable method for its production. This study focuses on enhancing HER efficiency through the fabrication of a Z-scheme based tungsten di sulfide/titanium di oxide (WS2/TiO2) he...

Dual functional heterostructure of Bismuth vanadate and Tungsten trioxide (BiVO 4 /WO 3) was developed and its use in the generation of hydrogen and the degradation of dyes was shown. BiVO 4 was synthesized by the sol gel method, and its heterostructure with WO 3 was created by the solvothermal method. To study the morphological, structural, and op...
Using hybrids and photon illumination together is an important step toward
making high-performance gas sensors. Hybrid materials have their own properties that can
improve the way gas sensors work, and photon illumination can make the sensor more
sensitive. There is currently a lack of understanding regarding the impact of photoassisted gas
sensing...
Two‐dimensional (2D) tungsten disulphide (WS2) based heterostructures with modified interfaces have huge potential for photocatalytic applications. Integrating WS2 with one‐dimensional (1D) titanium dioxide (TiO2) and 2D molybdenum disulphide (MoS2) structures to form heterostructures, enhances its photocatalytic activity. The enrichment in photoca...
In the quest to create effective sensors that operate at room temperature, consume less power and maintain their stability over time for detecting toxic gases in the environment, molybdenum disulfide (MoS2) and MoS2-based hybrids have emerged as potent materials. In this context, the current work describes the fabrication of Au-MoS2 hybrid gas sens...
The present study describes the synthesis of CdSe-incorporated TiO2 nanotubes (CdSe@TNT) via a modified hydrothermal method from CdSe-incorporated spherical TiO2 (CdSe@sTiO2). The structural and photocatalytic activities of both composites are then compared with spherical TiO2 (sTiO2). Quantum dots of CdSe are synthesized by varying Cd:Se precursor...
Molybdenum disulfide (MoS2) is one of the most potent transition metal dichalcogenide (TMDc) material
for gas sensing applications due to its various advantageous properties. It exhibits modest electron mobilities,

2D/1D-MoS2/TiO2 heterostructures have proven to be vigorous for photocatalytic applications. The enhancement in photocatalytic activity of heterostructures may get influenced by the accumulation of strain at the interface that affects the interfacial interaction. Keeping that in view, present paper reports the strain accumulated interfacial modific...
One dimensional nanostructures based hybrids have proven to be potent for photocatalytic applications. The hybrids having modified interface play a vigorous role in enrichment of photocatalytic activity by electronic interaction. Electronic interaction at interface occurs by the formation of electronic barriers (Ohmic/Schottky) that affects the tra...
Low energy ion-irradiated hybrid nanostructures with altered interfaces have sparked a lot of interest in the field of photocatalytic applications.

I have synthesized MoS2 nanoflowers using a hydrothermal method with ammonium molybdate as the Mo precursor and thiourea as the sulfur source. Additionally, I introduced oxalic acid into the reaction mixture. I'm curious to understand the role of oxalic acid in this synthesis. Specifically, can oxalic acid induce the creation of sulfur vacancies in the resulting MoS2 nanoflowers? I would appreciate insights or references related to this topic.
