We combine density functional theory simulations and sensing experiments to evaluate the gas detection performance of two transition metals dichalcogenides MoS2 and WS2. Specifically, we examine their sensitivity, detectivity, response and recovery times towards carbon dioxide (CO2), and carbon monoxide (CO). Our DFT simulations reveal remarkable s...

Visible-light-driven photocatalysis using layered materials has garnered increasing attention regarding the degradation of organic dyes. Herein, transition-metal dichalcogenides MoS 2 and WS 2 prepared by chemical vapor deposition as well as their intermixing are evaluated for photodegradation (PD) of methylene blue under solar simulator irradiatio...

Layered transition metals dichalcogenides such as MoS2 and WS2 have shown a tunable bandgap, making them highly desirable for optoelectronic applications. Here, we report on one-step chemical vapor deposited MoS2, WS2 and MoxW1-xS2 heterostructures incorporated into photo-conductive devices to be examined and compared in view of their use as potent...

Renewable energy-enabled desalination systems are crucial for solving the global water scarcity challenges in an environmentally friendly manner. In this work, we report an air gap membrane distillation (AGMD) process that utilizes polyvinylidene fluoride (PVDF) membranes blended with a photothermally active and relatively inexpensive activated car...

Molybdenum disulfide one of the graphene analogs and a typical representative of transition metal dichalcogenides, has recently received great attention due to its outstanding electrical and optical properties, such as the bandgap tuning, high carrier mobility and efficient optical absorption. Nanostructured Molybdenum disulfide for instance with s...
