Biopolymer-Coated Nanocatalyst Could Drive a Hydrogen Fuel-Based Future Image Credit: Shutterstock.com / peterschreiber.media A newly devised nanorod catalyst could help water splitting by sunlight become a viable and eco-friendly route to hydrogen fuel. Humanity’s consumption of fossil fuels drives massive detrimental changes to the environment, releasing carbon dioxide and other greenhouse gases into the atmosphere that are fueling the climate change crisis. Thus, a long-term sustainable alternative fuel source that is environmentally friendly is desperately needed. One possible alternative for fossil fuels that has been proposed by researchers for some time is hydrogen (H2). The Universe’s most abundant element, hydrogen, is a high-energy-density molecule, and when it is used as a fuel, it produces only water as a by-product making it a clean alternative to fossil fuels too. ....
E-Mail IMAGE: To realize a hydrogen fuel-based future, it is necessary to be able to produce it efficiently in an eco-friendly manner view more Credit: Incheon National University To combat climate change, shifting from fossil fuels to clean and sustainable energy sources is imperative. A popular candidate in this regard is hydrogen, an eco-friendly fuel that produces only water when used. However, the efficient methods of hydrogen production are usually not eco-friendly. The eco-friendly alternative of splitting water with sunlight to produce hydrogen is inefficient and suffers from low stability of the photocatalyst (material that facilitates chemical reactions by absorbing light). How does one address the issue of developing a stable and efficient photocatalyst? ....
