Recent demand for electric and hybrid vehicles, coupled with a reduction in prices, has caused lithium-ion batteries (LIBs) to become an increasingly popular form of rechargeable battery technology.

Hydrogen is one of the most important resources in providing food, fuel, and chemical products for our everyday life. Sustainable catalytic hydrogen production from bioethanol has gained significant attention in recent years due to globally diminishing fossil fuel supplies, which have necessitated the search for new chemical feedstocks.

Silica is a very popular inorganic nanomaterial used in a wide range of applications including fillers for rubber, catalyst supports, separation media, carriers in food and agriculture, and abrasive/anticaking agents in cosmetics. It is also widely believed to be an important material for biomedical applications for following reasons.

Solid oxide fuel cells and electrolyzers show potential for chemical-to-electrical energy conversion, despite early development stages.
