Hydrogen production by catalytic processes

The Effect of Addition Bisphenol-a-Polycarbonate From Cd-R Waste as a Catalyst for Hydrogen Production

“…NiOeNi/GCN nanocomposites have been found to be effective catalysts to increase hydrogen gas production, especially at the content of aromatic aldehydes [3]. In another study, adding an external magnetic field and graphene-activated carbon algae showed that the production of hydrogen gas obtained was doubled compared to conventional electrolysis methods [4].…”

Earth-Abundant-Based Photocatalysts for Efficient and Selective H2 Production through Reforming of Formic Acid under Visible Light

“…Nowadays, particular attention is directed to hydrogen, which is considered as one of the most promising future solar fuels because of its high energy density (∼120 MJ/kg) and wide availability on Earth in the form of water, organic matter, and hydrocarbons . To date, much effort has been undertaken to produce hydrogen via thermally driven processes in which decomposition of a given hydrogen source, such as liquid organic hydrogen carrier (LOHC), is catalyzed by supported metal species . From among various LOHC, particular attention has been paid to the production of hydrogen from formic acid (FAc) because of its low toxicity, nonflammability, availability, high stability, and high H 2 volumetric capacity (53 kg·m –3 ). − Typically, catalytic decomposition of FAc proceeds via two ways: (1) dehydrogenation (HCOOH → H 2 + CO 2 ) and (2) dehydration (HCOOH → CO + H 2 O) .…”
