“…Replacing the combustion heat in conventional fuel fired reformers with electrification is regarded as a very promising solution, also when considering the economically competitive prices of the renewable electricity compared with fossil fuels. − Process simulation results from different studies show that the novel electrified methane steam reforming process is of great interest from energy, environmental and economic point of view. ,,− The specific power consumption per hydrogen production estimated for electrified methane steam reforming (approximately 1 kWh/Nm 3 H2 considering only electric input) is remarkably lower than that in water electrolyzers (3.8–4.5 kWh/Nm 3 H2 ). , It should be noted that approximately 4% of the world’s hydrogen is derived from water electrolysis, whereas conventional methane steam reforming contributes to over 70% of the global hydrogen production . In this regard, the recent developments in direct Joule heating of methane reforming reactions are reviewed, as shown in Table .…”

The supply of the heat required for chemical processes via renewable electricity, i.e., process electrification, provides an alternative strategy for replacing conventional fossil fuel combustion. This approach enables fast, selective, and uniform heating, offers great potential for utilizing the excess renewable electric energy, and brings about an important chance for mitigating CO 2 emissions. In this work, we provide an overview of the state-of-the-art electricity-to-heat driven catalytic processes. The principle and fundamentals of Joule heating are provided and briefly compared to induction and microwave heating in view of electrifying catalytic processes. By this comparison, we assess that Joule heating can be regarded as the most promising method for process electrification, and its applications to methane reforming, cracking reactions, CO 2 valorization, and transient process operation are then reviewed. Advantages and disadvantages are critically addressed in terms of efficiency, potential for scale-up and possibility of retrofitting. The current challenges in the development of advanced electrified processes as well as the opportunities of next generation electrification techniques are discussed.

“…The growing global concern regarding the energy crisis and environmental pollution has sparked significant interest within the scientific and industrial communities in developing clean and sustainable energy alternatives to traditional fossil fuels [1,2]. Solar energy is an inexhaustible, clean and renewable natural resource, and hydrogen can serve as an energy carrier for solar energy with a high energy conversion efficiency and zero carbon, and the only byproduct is water.…”

The conversion of solar energy into hydrogen using photocatalysts is a pivotal solution to the ongoing energy and environmental challenges. In this study, inverse opal (IO) ZnIn2S4 (ZIS) with varying pore sizes is synthesized for the first time via a template method. The experimental results indicate that the constructed inverse opal ZnIn2S4 has a unique photonic bandgap, and its slow photon effect can enhance the interaction between light and matter, thereby improving the efficiency of light utilization. ZnIn2S4 with voids of 200 nm (ZIS–200) achieved the highest hydrogen production rate of 14.32 μ mol h−1. The normalized rate with a specific surface area is five times higher than that of the broken structures (B–ZIS), as the red edge of ZIS–200 is coupled with the intrinsic absorption edge of the ZIS. This study not only developed an approach for constructing inverse opal multi–metallic sulfides, but also provides a new strategy for enriching efficient ZnIn2S4–based photocatalysts for hydrogen evolution from water.

“…Electrocatalytic water cracking technology is one of the key technologies to achieve a clean and sustainable hydrogen energy framework in the future. 1 However, the process of hydrogen production by electrolysis of water has main disadvantages of high cost, 2 high energy consumption, and low energy conversion efficiency. 3 In the two half-reactions of water electrolysis, the oxygen evolution reaction (OER) of the anode has a higher kinetic barrier due to the four-electron transfer involved.…”
