“…[29] Non-precious co-catalysts were shown to be superior over Pt, with aM oS 2 /CdS composite [30] [32] and Fe 2 O 3 /Si (4.42 mmol H 2 g cat À1 h À1 ) [33] have shown promising activities for visible-light driven glucose PR. Other suitable materials include LaFeO 3 , [34] Bi x Y 1-x VO 4 , [35] CaTa 2 O 6 , [36] La:NaTaO 3 , [37] and SrTiO 3 .…”

Photocatalytic reforming of lignocellulosic biomass is an emerging approach to produce renewable H 2 . This process combines photo‐oxidation of aqueous biomass with photocatalytic hydrogen evolution at ambient temperature and pressure. Biomass conversion is less energy demanding than water splitting and generates high‐purity H 2 without O 2 production. Direct photoreforming of raw, unprocessed biomass has the potential to provide affordable and clean energy from locally sourced materials and waste.

“…Perovskite-type LaFeO 3 has been used for the PR of glucose with an H 2 evolution efficiency of 1600 μmol H 2 g cat –1 h –1 . Similarly, the tantalates CaTa 2 O 6 and La:NaTaO 3 with perovskite structure, which has been used as photocatalysts for hydrogen generation because of their absorption tailing into the visible range, showed a promising PR of glucose. , Pt-loading SrTiO 3 provided a high PR activity (276 μmol H 2 g cat –1 h –1) for UV and visible light …”

Energy from renewable resources is central to environmental sustainability. Among the renewables, sunlight-driven fuel synthesis is a sustainable and economical approach to produce vectors such as hydrogen through water splitting. The photocatalytic water splitting is limited by the water oxidation half-reaction, which is kinetically and energetically demanding and entails designer photocatalysts. Such challenges can be addressed by employing alternative oxidation half-reactions. Photoreforming can drive the breakdown of waste plastics and biomass into valuable organic products for the production of H 2 . We provide an overview of photoreforming and its underlying mechanisms that convert waste polymers into H 2 fuels and fine chemicals. This is of paramount importance from two complementary perspectives: (i) green energy harvesting and (ii) environmental sustainability by decomposing waste polymers into valuables. Competitive results for the generation of H 2 fuel without environmental hazards through photoreforming are being generated. The photoreforming process, mechanisms, and critical assessment of the field are scarce. We address such points by focusing on (i) the concept of photoreforming and up-to-date knowledge with key milestones achieved, (ii) uncovering the concepts and challenges in photoreforming, and (iii) the design of photocatalysts with underlying mechanisms and pathways through the use of different polymer wastes as substrates.

Die photokatalytische Reformierung Lignocellulose‐haltiger Biomasse ist eine aufstrebende Methode zur Produktion von erneuerbarem H2. Dieser Prozess verbindet Photooxidation von Biomasse mit photokatalytischer Wasserstoffentwicklung bei Raumtemperatur und Atmosphärendruck. Die Umsetzung von Biomasse ist weniger energieaufwändig als Wasserspaltung und liefert dabei hochreinen H2, ohne dass sich O2 bildet. Die direkte Reformierung von unbehandelter Rohbiomasse birgt das Potenzial, weltweit lokal verfügbares Material als kostengünstige Energiequelle zu nutzen.
