Hydrogen is considered to be an ideal energy carrier to achieve low-carbon economy and sustainable energy supply. Production of hydrogen by catalytic reforming of organic compounds is one of the most important commercial processes. With the rapid development of photocatalysis in recent years, the applications of photocatalysis have been extended to the area of reforming hydrogen evolution. This research area has attracted extensive attention and exhibited potential for wide application in practice. Photocatalytic reforming for hydrogen evolution is a sustainable process to convert the solar energy stored in hydrogen into chemical energy. This review comprehensively summarized the reported works in relevant areas, categorized by the reforming precursor (organic compound) such as methanol, ethanol and biomass. Mechanisms and characteristics for each category were deeply discussed. In addition, recommendations for future work were suggested.

Hydrogen as the most promising alternative energy vector to fossil stands out due to its highly energy density and zero pollution. Extending the hydrogen feedstock from hydrocarbons (e. g., methane) to biomass derived oxygen‐containing compounds (CH3OH, C2H5OH etc.) provides the opportunity for low environmental pollution as well as a promising sustainable energy economy. Recently, ethanol with less toxic and high calorific value than traditional fossil energy (coal, oil and natural gas) has garnered significant attention for ethanol steam reforming (ESR) to produce hydrogen, a key component in fuel cell cogeneration system. This paper reviews recent advances on the catalyst developing strategies including structural constitution control, oxide supports modification, surface topography control and bimetallic interactions, and further discusses the catalytic mechanisms, anti‐carbon deposition and sintering resistance strategies on the ethanol steam reforming (ESR) processes. Finally, the challenges and possible strategies for the development of high‐performance catalysts in terms of fundamental research have been discussed.

“…Moreover, non‐metals have been employed as promoters. The preparation method of co‐precipitation of boron (B) and Ce 0.5 Zr 0.5 O 2 ‐supported Ni‐based catalysts enhances the dispersion of the active species and forms a Ni‐B alloy, promoting the catalytic performance of the ESR for hydrogen production . The B‐doped catalysts also improve the stability of the catalyst by introducing CeBO 3 , which possesses a high oxygen storage capacity in order to react with the carbon species formed during the ESR reaction .…”

Ethanol steam reforming (ESR) is one of the potential processes to convert ethanol into valuable products. Hydrogen produced from ESR is considered as green energy for the future and can be an excellent alternative to fossil fuels with the aim of mitigating the greenhouse gas effect. The ESR process has been well studied, using transition metals as catalysts coupled with both acidic and basic oxides as supports. Among various reported transition metals, Ni is an inexpensive material with activity comparable to that of noble metals, showing promising ethanol conversion and hydrogen yields. Additionally, different promoters and supports were utilized to enhance the hydrogen yield and the catalyst stability. This review summarizes and discusses the influences of the supports and promoters of Ni‐based catalysts on the ESR process.
