“…84 In addition, the peaks of Co at 786.4 and 802.5 eV can be ascribed to Co 2+ , indicating that metallic Co was easy to be oxidized instead of Ni. 85,86 The oxidation deactivation of 6% Ni−4% Co/char nanocatalyst was preferable to the oxidation of metallic Co species rather than Ni species because of the high oxygen affinity of Co, as reported by other studies. 50,51 The strengthened interaction between Ni and Co in the Ni−Co alloy, high dispersion of Ni nanoparticles, and high oxygen affinity of Co were beneficial to suppress agglomeration sintering and oxidation deactivation of active particles Ni loading on 6% Ni−4% Co/char.…”

Hydrogen (H 2 ) production from coal and biomass gasification was considered a long-term and viable way to solve energy crises and global warming. Tar, generated as a hazardous byproduct, limited its large-scale applications by clogging and corroding gasification equipment. Although catalytic steam reforming technology was used to convert tar into H 2 , catalyst deactivation restricted its applicability. A novel nanocatalyst was first synthesized by the modified sol−gel method using activated biochar as the support, nickel (Ni) as the active component, and cobalt (Co) as the promoter for converting tar into H 2 . The results indicated that a high H 2 yield of 263.84 g H 2 / kg TMCs (Tar Model Compounds) and TMC conversion of almost 100% were obtained over 6% Ni−4% Co/char, with more than 30% increase in hydrogen yield compared to traditional catalysts. Moreover, 6% Ni−4% Co/char exhibited excellent resistance to carbon deposition by removing the nucleation sites for graphite formation, forming stable Ni−Co alloy, and promoting the char gasification reaction; resistance to oxidation deactivation due to the high oxygen affinity of Co and reduction of the oxidized nickel by H 2 and CO; resistance to sintering deactivation by strengthened interaction between Ni and Co, high specific surface area (920.61 m 2 /g), and high dispersion (7.3%) of Ni nanoparticles. This work provided a novel nanocatalyst with significant potential for long-term practical applications in the in situ conversion of tar into H 2 during steam reforming.

Water splitting technology is an innovative strategy to face the dependency on fossil fuels and, at the same time, address environmental pollution issues. Electrocatalysts seem to be the better option to improve water separation efficiency and satisfy the commercial-scale demand for hydrogen. Therefore, the design and fabrication of heterostructures with a high affinity for achieving water splitting have been proposed. In this review, the application of several electrocatalysts for hydrogen and oxygen evolution reactions is presented and discussed in detail. A review of the recent advances in water separation using noble metals such as Pt-, Ir-, and Ru-based electrodes is presented, followed by a highlighting of the current trends in noble-metal-free electrocatalysts and novel preparation methods. Furthermore, it contemplates some results of a hybrid organic molecule–water electrolysis and photoelectrochemical water splitting. This review intends to give insight into the main trends in water splitting and the barriers that need to be overcome to further boost the efficiency of the main hydrogen and oxygen generation systems that ultimately result in large-scale applications. Finally, future challenges and perspectives are addressed, considering all the novelties and the proposed pathways for water splitting.
