Research Progress for Hydrogen Evolution from Formaldehyde

Hydrogen is a high energy density carrier with renewable and zero emission characteristics. It is thought to be one of the most ideal energy carriers to replace traditional fossil fuels in the future. Compared with other hydrogen carriers, formaldehyde can be easily produced in large-scale from plant of sources, and is safety in transportation, storage and conversion. It becomes a new raw material for hydrogen production on-site. In addition, the technology of hydrogen production from formaldehyde can be also applied in the conversion of toxic organic compounds into clean hydrogen. This article summarizes the research and development progresses of formaldehyde industrial preparation, catalytic conversion to hydrogen and catalyst investigations in recent years, analyzes and compares the characters of various technologies in formaldehyde catalytic hydrogen production. Finally, the prospect of catalytic conversion of formaldehyde to hydrogen is discusssed.
