“…To this end, sensor stability is usually examined by exposing the sensor to a large number of hydrogen cycles or by intermittent testing over a long period of time. 58 , 91 , 112 To the best of our knowledge, no specific recommendation for the minimal number of cycles exists, but we would recommend at least 50 cycles for such tests, ideally more.…”

Hydrogen gas is rapidly approaching a global breakthrough as a carbon-free energy vector. In such a hydrogen economy, safety sensors for hydrogen leak detection will be an indispensable element along the entire value chain, from the site of hydrogen production to the point of consumption, due to the high flammability of hydrogen–air mixtures. To stimulate and guide the development of such sensors, industrial and governmental stakeholders have defined sets of strict performance targets, which are yet to be entirely fulfilled. In this Perspective, we summarize recent efforts and discuss research strategies for the development of hydrogen sensors that aim at meeting the set performance goals. In the first part, we describe the state-of-the-art for fast and selective hydrogen sensors at the research level, and we identify nanostructured Pd transducer materials as the common denominator in the best performing solutions. As a consequence, in the second part, we introduce the fundamentals of the Pd–hydrogen interaction to lay the foundation for a detailed discussion of key strategies and Pd-based material design rules necessary for the development of next generation high-performance nanostructured Pd-based hydrogen sensors that are on par with even the most stringent and challenging performance targets.

Biohydrogen is regarded as an attractive future clean energy carrier due to its high energy content and environmentally friendly conversion. Biohydrogen reactor is widely used in studies concerning the anaerobic co-digestion of food waste, sewage sludge, wastewater and other organic solids. Anaerobic digestion is a series of biological processes in which microorganisms break down biodegradable material (biomass or waste feedstock) in the absence of oxygen to produce biogas, which may generate electricity and heat, or can be processed into renewable natural gas and transportation fuels. This review article explains the scientific processes of anaerobic digestion process such as hydrolysis, acidogenesis, acetogenesis and hydrogenesis as well as methods to produce biohydrogen gas such as fermentation and biophotolysis for the waste management technology and sources of renewable energy and concludes with solutions that may allow anaerobic digestion to become more widely adopted throughout the developing countries to control the waste management system.

“…It is therefore worthwhile to explore novel treatments, new processes, and alternative material combinations. In this study, Au NPs were added to ZnO/ZnS core-shell nanostructures to optimize the material properties and sensing applications [17][18][19]. A new nanocomposite with the addition of Au NPs could further enhance UV light/hydrogen gas dual sensitivity and shorten the gas/light response/recovery time owing to electrical and optical enhancements.…”

“…A new nanocomposite with the addition of Au NPs could further enhance UV light/hydrogen gas dual sensitivity and shorten the gas/light response/recovery time owing to electrical and optical enhancements. The detection of skin cancer-causing UV light [17] and monitoring of inflammable hydrogen gas [18,19] are crucial to environmental safety. Owing to their compact size, simple fabrication, and good sensing performance, ZnO/ZnS/Au NPs-based UV light/hydrogen gas dual sensors are promising for future environmental and detectional use.…”

Incorporation of Au Nanoparticles on ZnO/ZnS Core Shell Nanostructures for UV Light/Hydrogen Gas Dual Sensing Enhancement

ZnO/ZnS nanocomposite-based nanostructures exhibit dual light and gas sensing capabilities. To further boost the light/dual sensing properties, gold nanoparticles (Au NPs) were incorporated into the core-shell structures. Multiple material characterizations revealed that Au NPs were successfully well spread and decorated on ZnO/ZnS nanostructures. Furthermore, our findings show that the addition of Au NPs could enhance both 365 nm UV light sensing and hydrogen gas sensing in terms of light/gas sensitivity and light/gas response time. We postulate that the optimization of gas/light dual sensing capability may result from the induced electric field and inhabitation of electron-hole recombination. Owing to their compact size, simple fabrication, and stable response, ZnO/ZnS/Au NPs-based light/gas dual sensors are promising for future extreme environmental monitoring.
