“…A lower reduction temperature of active species, which is important for the redox mechanism in the WGS reaction, increased in the following order: Cu–NC < Co–NC < Fe–NC < Zn–NC. Easier reducibility of a catalyst helps to enhance its activity, especially at low temperature in a redox reaction . In the WGS reaction, redox behavior is considered as a reliable reaction mechanism …”

“…The Co–NC–SG catalyst was prepared using citric acid. ,, The precursors of Co, Ce, and citric acid were dissolved in 20 mL of deionized water, and the Nb precursor was dissolved in 10 mL of ethanol. After mixing the two solutions, the mixture was heated to 80 °C and stirred at 400 rpm using a 3.5 cm magnetic bar.…”

“…Hydrogen is considered an eco-friendly energy carrier because it emits only water when oxidized. − However, currently, hydrogen is produced by chemical reactions using fossil fuels (95–96% of total production), such as natural gas reforming, partial oil oxidation, and coal gasification. , Consequently, finding new means to produce hydrogen that do not rely on fossil fuels is necessary to maximize the environmental benefits . With this in mind, hydrogen production from waste has received considerable attention because the process can improve both sustainability and the diversity of hydrogen supply.…”

A comparative study to obtain a cost-competitive catalyst was performed to produce hydrogen via the high temperature water gas shift (WGS) reaction using synthesis gas (syngas) derived from waste. First, several selected active metals on Nb−CeO 2 support and preparation methods were applied to prepare highly active and stable catalysts under severe reaction conditions. Various characterization methods were employed to understand the correlation between catalytic activity and physicochemical properties of the prepared catalysts. Among the Me−Nb−CeO 2 (Me = Co, Cu, Fe, and Zn) catalysts, Co−Nb− CeO 2 showed the highest activity at a high gas hourly space velocity of 315,282 mL•g −1 •h −1 (temperature = 500 °C, X CO ≈ 84%). This was attributed to the high Brunauer−Emmett−Teller surface area and oxygen storage capacity of the Co−Nb−CeO 2 catalyst. In addition, to investigate the effect of preparation method, various methods, including coprecipitation, incipient wetness impregnation, sol−gel, and hydrothermal methods, were applied for the synthesis of the Co−Nb−CeO 2 catalyst. The Co−Nb− CeO 2 catalyst prepared using the coprecipitation method exhibited high activity without significant deactivation for 60 h. This was attributed to the high oxygen storage capacity and intimate interaction between Co and the Nb−CeO 2 support. Finally, technoeconomic analysis and environmental impact assessment were performed for the Co−Nb−CeO 2 catalysts, prepared by different preparation methods to identify the most promising catalyst for the production of hydrogen using the syngas derived from waste. By comparison with a commercial catalyst, it was shown that Co−Nb−CeO 2 synthesized using coprecipitation is a promising, costeffective, and eco-friendly catalyst with high activity.

“…The renewable energy should be satisfied to overcome the current problems resulted from fossil fuels using like the price rising, air pollution and global warming. Hydrogen is one of the clean renewable energy and recognized as a common potential fuel for many petro-chemical industries during the last 20 years [2]. Hydrogen demand is increasing as a potential renewable energy source for its clean combustion and its high specific energy (~123 MJ/kg) comparing to fossil fuels (~46 MJ/kg) [3].…”

Biohydrogen production by fermentative bacteria is one of the most prospective alternative ways for fossil fuels. Therefore, this study aimed to isolate new facultative anaerobic bacteria from cow rumen as highly hydrogen producers from sugarcane molasses. Among the isolated ruminant anaerobic bacteria, the isolate RM92 was the highest hydrogen producer with maximum cumulative hydrogen (Hmax) of 426.67±14.56 mL/L. This bacterial isolate (RM92) was identified phenotypically and genotypically as Escherichia fergusonii. The 16S rRNA gene sequence was deposited in NCBI GenBank database under the accession number OP185369. Optimization expermients design for maximization of hydrogen production by E. fergusonii RM92 increased the Hmax to 1280.00 ±34.64 ml/L with maximum hydrogen production rate (Rmax) of 36.92±0.89 ml/L/h on 4% molasses sugar concentration, pH 8, incubation temperature 40 °C and initial inoculum size 30% (v/v). These findings suggest that E. fergusonii RM92 could be used as a potential hydrogen producer from cheap agro-industrial wastes.

Sustainability has become one of the greatest scientific challenges of our time. Redesigning the chemical value chain with sustainable reactions and non‐fossil feedstocks, closing cycles in energy storage and digitalization demand interdisciplinary scientific excellence. The summer school organized by the early career researchers groups of Germanys reaction engineering and catalysis community aimed to bring together young scientists from reaction engineering and catalysis with experts from industry and academia to work on sustainable chemistry, energy storage and digitalization. During three days of lectures, workshops and intensive group work, the hot topics of our time were discussed and seminal ideas to tackle current challenges were formed.
