This work describes the effect of solvents used for solvothermal reactions to synthesize quaternary copper–iron–tin sulfide (Cu 2 FeSnS 4 ) nanosheets that can serve as a potential alternative divergent energy conversion device applications.
The weight reduction of the bipolar plate (BP) is essential for commercializing unitized regenerative fuel cells (URFCs). In order to lighten plate, we have used Pb/C composite powder as a cost-effective primary material, which mixture low-density graphite and lead. Further, varied lead-carbon ratios (1: 8, 1:4, 1:1, 4:1, 8:1) were investigated fabricating by hot-pressing process adding styrene-butadiene rubber (SBR) binder. specific surface area, porosity, microstructure characteristics...
Hydrogen energy from water splitting is considered the highly anticipated modern resource; however, storage and transportation require complex high‐cost facilities, which argue about efficiency of hydrogen fuel compared to conventional fuels. Thereby, ammonia (NH 3 ), a liquid at ambient conditions, promises lower cost transportation, but production imposes difficulties with selectivity over several products and, notably, evolution reaction. Among methods combining advantages electrochemical...
The size of the urea market is more than $131.54 billion in 2023 and continues to grow. However, production highly relies on traditional Bosch-Meiser process, which utilizes CO 2 NH 3 under harsh conditions, contributing over 1% energy consumption world. To solve this issue, electrochemical has gained attention for its cost-effective eco-friendly properties. synthesis from nitrate (NO - ) necessitates improvements both NO reduction reaction reaction. In study, CuFe nanoparticles (NPs) are...
Carbon neutrality using cleaner energy sources to replace fossil fuels is essential for climate change and a sustainable future. There are many candidates, including renewable energy, but hydrogen gaining the most attention. Hydrogen attractive alternative due its abundance, renewability, eco-friendliness as an source, however, utilization limited by transportation challenges. To solve this issue, various carriers have been studied. Among them, ammonia considered closest commercialization...
Reducing carbon emissions is important for sustainable development, and most occur during the production use of fossil fuel-based energy. In order to reduce emissions, it essential discover new energy sources without emissions. There are several candidates, including renewable energy, but realistic hydrogen abundant as an source, renewable, environmentally friendly. However, has a loss problem transportation process, this needs be supplemented. To solve issue, various carriers have been...
The replacement of fossil fuels is urgently needed for carbon neutrality and sustainable development. Hydrogen represented as a next-generation energy source, among the various methods to obtain hydrogen, water electrolysis using catalysts has been studied steadily. Among them, photoelectrochemical solar promising method, but it problems such high overvoltage, durability photoelectrodes under aqueous electrolyte environment, photocorrosion. Therefore, recently, there increasing interest in...
