The gasification of biomass with supercritical water, also known as SCWG, is a sustainable method of hydrogen production. The process produces a mixture of hydrogen, carbon oxides, and hydrocarbons. Upgrading this mixture through steam or dry reforming of hydrocarbons to create synthesis gas and then extra hydrogen is a viable way to increase hydrogen production from biomass. This literature review discusses combining these two processes and recent experimental work on catalytic SCWG of biomass and its model compounds and steam/dry reforming of produced hydrocarbons. It focuses on catalysts used in these processes and their key criteria, such as activity, selectivity towards hydrogen and methane, and ability to inhibit carbon formation and deposition. A new criterion is proposed to evaluate catalyst performance in biomass SCWG and the need for further upgrading via reforming, based on the ratio of hydrogen bound in hydrocarbons to total hydrogen produced during SCWG. The review concludes that most catalysts used in biomass SCWG trap a large proportion of hydrogen in hydrocarbons, necessitating further processing of the product stream.

“…Therefore, other methods where size, shape, and purity can be improved are favored. Titanatebased perovskites have offered applications in the area of photocatalytic hydrogen production and hydrocarbon reforming (Hbaieb et al, 2017). According to Zhang et al (2007), the perovskite structure consisting of oxygen octahedral, such as TiO 6 , seems to play an important role for active photocatalysts, and the band edge positions, width of the conduction band, bandgap, and migration of photogenerated charge carriers as well as the photocatalytic activities are closely related to the distortion and the connectivity of the MO 6 (M Ti 4+ , Nb 5+ , and Ta 5+ ) octahedra in perovskite titanates, niobates, and tantalates.…”

Meeting the global challenge of water availability necessitates diversification from traditional water treatment methods to other complementary methods, such as photocatalysis and photoelectrocatalysis (PEC), for a more robust solution. Materials play very important roles in the development of these newer methods. Thus, the quest and applications of a myriad of materials are ongoing areas of water research. Perovskite and perovskite-related materials, which have been largely explored in the energy sectors, are potential materials in water treatment technologies. In this review, attention is paid to the recent progress in the application of perovskite materials in photocatalytic and photoelectrocatalytic degradation of organic pollutants in water. Water treatment applications of lanthanum, ferrite, titanate, and tantalum (and others)-based perovskites are discussed. The chemical nature and different synthetic routes of perovskites or perovskite composites are presented as fundamental to applications.

“…As with almost all chemical processes, the choice of a suitable ATR catalyst is decisive for the complete conversion of carbonaceous feedstocks and promising long-term stability. In the relevant literature, Rh, Pt, Ru, Ir and Ni are deposited on different washcoats such as Al2O3, SiO2, CeO2, ZrO2 or perovskites, and have been found to best fulfill the requirements of high activity and stability [30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47]. High activity and stability, however, are threatened by the above-mentioned coke deposits and, additionally, by adsorbing sulfur-and phosphorouscontaining components, which might block the catalytically-active sites on the catalyst surface being no longer accessible for the reactants.…”
