The overuse of fossil fuels has caused a serious energy crisis and environmental pollution. Due to these challenges, the search for alternative energy sources that can replace fossil fuels is necessary. Hydrogen is a widely acknowledged future energy carrier because of its nonpolluting properties and high energy density. To realize a hydrogen economy in the future, it is essential to construct a comprehensive hydrogen supply chain that can make hydrogen a key energy carrier. This paper reviews the various technologies involved in the hydrogen supply chain, encompassing hydrogen production, storage, transportation, and utilization technologies. Then, the challenges of constructing a hydrogen supply chain are discussed from techno-economic, social, and policy perspectives, and prospects for the future development of a hydrogen supply chain are presented in light of these challenges.

“…(i) The absorption of light, (ii) the generation and migration of electron–hole pairs, and (iii) the occurrence of surface redox reactions. 11,113 Semiconductor materials possess a significantly narrower band gap between the valence band (VB) and the conduction band (CB) when compared to insulators. This narrower band gap enables photons with energy equal to or greater than the semiconductor's band gap energy to excite and mobilize electrons within the material, setting the stage for subsequent photocatalytic reactions.…”

Reasonable adjustment of the exposed crystal facets has been proven to be an effective strategy to improve the activity of the catalyst. However, the crystal-facet-dependent piezoactivity is rarely investigated. In this work, BiFeO 3 with highly exposed (012) or (110) crystal facets were synthesized by adjusting the volume ratio of solvent and reaction time. Ethylene glycol was used as a structure-directing agent for the synthesis of BiFeO 3 nanosheets (BiFeO 3 −NS) with highly exposed (012) facets. BiFeO 3 −NS shows an obvious higher piezoelectric catalytic hydrogen evolution rate than that of BiFeO 3 nanoparticles (BiFeO 3 − NP) with highly exposed (110) facets. In addition, the rate constant of BiFeO 3 −NS for the piezocatalytic degradation of rhodamine B (RhB) shows a 2-fold increase than that of BiFeO 3 −NP. A variety of controlled experiments have been performed. It is revealed that these two nanomaterials exhibit comparable specific surface areas and adsorption capacity. BiFeO 3 −NS possesses narrowed bandgap as compared to that of BiFeO 3 −NP. The enhanced piezocatalytic activity of BiFeO 3 −NS can be attributed to its built-in electric field, strong carrier mobility, and effective charge separation efficiency. This study provides an alternative perspective for piezoelectric catalysis in surface engineering.
