“…For instance, although Cu/ZnO/Al2O3, commonly used in commercial methanol synthesis, exhibits high activity, its stability decreases at high temperatures, leading to natural ignition, sintering, and deactivation. Consequently, various studies have been conducted to improve stability [94,95,104]. Cu-based catalysts typically involve a reaction between oxygen and hydrogen at two adsorption sites, as shown in Figure 3 [89].…”

“…The dehydrogenation reactions required to get hydrogen from chemical hydrogen carriers commonly employ catalysts such as Fe, Ni, Pt, and Ru to promote exothermic reactions. Therefore, the development of catalysts enabling higher hydrogen production rates and efficiency at lower temperatures, along with high-purity hydrogen extraction, is imperative [82][83][84][85][86][87][88][89][90][91][92][93][94][95][96]. The hydrogen produced requires refinement, with coupling to existing commercial hydrogen production methods such as Steam Methane Reforming (SMR) with separation and purification facilities allowing for cost savings in hydrogen production by separating carbon monoxide and carbon dioxide [97][98][99][100][101][102][103][104][105][106][107][108][109][110][111].…”

In light of climate change imperatives, there arises a critical need for technological advancements and research endeavors towards clean energy alternatives to replace conventional fossil fuels. Additionally, the development of high-capacity energy storage solutions for global transportability becomes paramount. Hydrogen emerges as a promising environmentally sustainable energy carrier, devoid of carbon dioxide emissions and possessing a high energy density per unit mass. Its versatile applicability spans various sectors including industry, power generation, and transportation. However, the commercialization of hydrogen necessitates further technological innovations. Notably, high-pressure compression for hydrogen storage presents safety challenges and inherent limitations in storage capacity about 30%–50% lost production of hydrogen. Consequently, substantial research endeavors are underway in the domain of material-based chemical hydrogen storage that reactions to occur at temperatures below 200 ℃. This approach enables the utilization of existing infrastructure, such as fossil fuels and natural gas, while offering comparatively elevated hydrogen storage capacities. This study aims to introduce recent investigations concerning the synthesis and decomposition mechanisms of chemical hydrogen storage materials, including methanol, ammonia, and Liquid Organic Hydrogen Carrier (LOHC).

“…Obviously, the supported perovskite catalysts were achieved at lower temperature with comparable time in comparison with other methods, including sol–gel, microwave-assisted, and citrate methods. NiTiO 3 have become efficient and robust host oxides since they contain both metal nanoparticles and counterpart support from subsequent topotactic exsolution processes. − Highly dispersed metal nanoparticles could grow in situ and be anchored on the surface of the catalyst. Smal et al synthesized a series of 5% Ni/Ce 1– x Ti x O 2 catalysts via an impregnation method.…”

Design of Ni catalysts with carbon resistance by well diminishing the carbon deposition rate remains a great challenge for dry reforming of methane (DRM). Herein, Ni 1−x Co x bimetallic (x = 0.1, 0.2) catalysts were prepared by the impregnation method. In-situ XRD was used to reveal the transformation from precursor TiC to NiTiO 3 /TiO 2 and Ni 1−x Co x TiO 3 /TiO 2 (x = 0.1, 0.2) with perovskite structure during calcination at 700 °C. Compared to monometallic Ni/TiO 2 after reduction, Ni 0.8 Co 0.2 /TiO 2 and Ni 0.9 Co 0.1 /TiO 2 after subsequent reduction exhibited higher initial catalytic activity. Furthermore, Ni 0.9 Co 0.1 /TiO 2 possessed superior stability with CH 4 and CO 2 conversions of 30% and 46%, respectively, in comparison with the decline of catalytic performance on Ni 0.8 Co 0.2 /TiO 2 in DRM at 700 °C for 10 h. The main origin for the enhanced stability on the former catalyst was originated from no carbon deposition, as evidenced by the restricted CH 4 dissociation at 503 °C and the promoted CO 2 activation via more available oxygen vacancies on bimetallic Ni 0.9 Co 0.1 /TiO 2 .
