Hydrogen, essential for clean and sustainable energy solutions, encounters significant challenges in electrochemical water splitting. This study introduces a Z-Scheme WS2/TiO2 heterostructure synthesized via a hydrothermal method, aimed at enhancing hydrogen evolution reaction (HER) performance through interface engineering. Comprehensive interfaci...

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...
