“…Perovskite is defined in the form of ABO 3 , where A and B present the rare-earth cation and transition metal, respectively. The corners of the unit cell are generally concurred by the A sites while B sites are placed in the center with a coordination number of 12 and 6, respectively [87]. Perovskite type oxides have received significant attention because of their unique crystal structures in chemical processes such as steam reforming of various hydrocarbons such as methane, ethanol, and glycerol [88][89][90][91].…”

In the last decades, environmental crises and increasing energy demand have motivated researchers to investigate the practical techniques for the production of clean fuels through renewable energy resources. It is essential to develop technologies to utilize glycerol as a byproduct derived from biodiesel. Glycerol is known as a sustainable and clean source of energy, which can be an alternative resource for the production of value-added chemicals and hydrogen. The hydrogen production via steam reforming (SR) of glycerol using Ni-based catalysts is one of the promising approaches for the entry of the hydrogen economy. The purpose of this review paper is to highlight the recent trends in hydrogen production over Ni-based catalysts using the SR of glycerol. The intrinsic ability of Ni to disperse easily over variable supports makes it a more viable active phase for the SR catalysts. The optimal reaction conditions have been indicated as 650–900 °C, 1 bar, and 15 wt% Ni in catalysts for high glycerol conversion. In this review paper, the effects of various supports, different promoters (K, Ca, Sr, Ce, La, Cr, Fe), and process conditions on the catalytic performance have been summarized and discussed to provide a better comparison for the future works. It was found that Ce, Mg, and La have a significant effect on catalytic performance as promoters. Moreover, SR of glycerol over hydrotalcite and perovskite-based catalysts have been reviewed as they suggest high catalytic performance in SR of glycerol with improved thermal stability and coke resistance. More specifically, the Ni/LaNi0.9Cu0.1O3 synthesized using perovskite-type supports has shown high glycerol conversion and sufficient hydrogen selectivity at low temperatures. On the other hand, hydrotalcite-like catalysts have shown higher catalytic stability due to high thermal stability and low coke formation. It is vital to notice that the primary concern is developing a high-performance catalyst to utilize crude glycerol efficiently.

“…The staggering number of oxide perovskites compositions motivates the need for high-throughput research methods to discover the most promising perovskites for STCH application and the need to probe composition–structure–property relations that can improve understanding of the STCH process. Numerous studies have sought new STCH perovskites using high-throughput computational methods. , However, experimental (combinatorial) high-throughput methods have been less explored for perovskites in STCH compared to other applications (e.g., piezoelectrics). In addition to the combinatorial screening for STCH application studied here, the oxide perovskite crystal structure and redox properties show great promise for a wide range of other applications, including fuel cells, catalysis, and electrochemical water-splitting …”

Double-Site Substitution of Ce into (Ba, Sr)MnO₃ Perovskites for Solar Thermochemical Hydrogen Production

Solar thermochemical hydrogen production (STCH) is a renewable alternative to hydrogen production using fossil fuels. While serial bulk experimental methods can accurately measure STCH performance, screening chemically complex materials systems for new promising candidates is more challenging. Here we identify double-site Ce-substituted (Ba,Sr)MnO3 oxide perovskites as promising STCH candidates using a combination of bulk synthesis and high-throughput thin-film experiments. The Ce substitution on the B-site in 10H-BaMnO3 and on the A-site in -SrMnO3 leads to 2–3 times higher hydrogen production compared to CeO2, but these bulk single-site substituted perovskites suffer from incomplete reoxidation. Double-site Ce substitution on both A- and B-sites in (Ba,Sr)MnO3 thin films increases Ce solubility and extends the stability of 10H and 3C structures, which is promising for their thermochemical reversibility. This study demonstrates a high-throughput experimental method for screening complex oxide materials for STCH applications.

“…High-throughput approaches of synthesising materials have become an important approach to rapidly assess larger compositional ranges of material systems and are seen in all aspects of material science [32]. Combinatorial approaches have used atomic deposition processes to produce thin film samples with continuous or discrete compositional variations [33,34]. There has been work in applying high-throughput methodologies to tape cast materials, which have a length scale similar to a dielectric ceramic layer in multi-layer ceramic capacitors [35].…”
