Doping of carbon nanotubes (CNTs) effectively provides a route to tune their
physicochemical properties towards specific applications. Heteroatoms, such as boron (B) …

Storage is a challenging issue that cuts across distribution, delivery, and safe end-uses of
hydrogen as fuel. All the fuel cell vehicles are equipped with inefficient and unsafe high …

We take a fresh look at the major nonrenewable and renewable energy sources and
examine their long-term viability, scalability, and the sustainability of the resources that they …

Hydrogen as an energy source has gained a considerable interest because of its potential to
minimize carbon emissions. The storage of hydrogen is the key for establishing a hydrogen …

The spinel type compounds represent a new family of photocatalysts that can be used as
photoelectrodes capable to produce hydrogen under visible light. In the current study, the …

The present investigation reports the synthesis of graphene quantum dots (GQDs) by the
microwave-assisted green synthesis method, and its catalytic effect in improving the …

Advances covers biological hydrogen production authoritatively from A to Z, including
microbiology, hydrogen production processes, biohydrogen feedstocks, molecular biology of …

Abstract Ni–Co/ZrO 2 (NCZ) nano-structure catalysts prepared by the hydrothermal method
(NCZ-hyd) and conventional impregnation (NCZ-imp) method. The comparative catalytic …

The port-injection-type hydrogen engine is advantaged in that hydrogen gas is injected into
the intake pipe through a low-pressure fuel injector, and the mixing period with air is …
