“…Due to the high oxidation rate of non-precious metal NPs, the direct use of non-precious metal oxides as AB dehydrogenation catalysts has received much attention in recent years. [226][227][228] In 2018, Liu and co-workers reported a mixed nanocatalyst containing heterostructures and only non-precious metals (expressed as Cu@Cu-CoO x @GO), and the hydrogen generation efficiency of the yielded catalyst in the hydrolysis of AB was demonstrated. 229 The best TOF of 44.6 min −1 was provided by Cu 0.3 @Cu 0.7 CoO x @GO and the TOF could be further increased with NaOH addition (98.2 min −1 ) at room temperature.…”

Hydrogen, as a clean and efficient energy source, is one of the important energy carriers in the future. However, the safe storage and delivery of hydrogen is still a bottleneck in its practical applications. Chemical hydrides (such as NaBH4, NH3BH3, N2H4·H2O, N2H4BH3, and HCOOH) are considered as potential chemical hydrogen storage materials that can achieve rapid on‐site hydrogen production. At present, the most critical issue for them is to develop economic catalysts to achieve efficient hydrogen production from chemical hydrides. Copper (Cu) is considered as a promising catalyst that is one of the most reactive metals among the first‐row transition metals and economically cheap. In this review, we outline the recent advancements of Cu‐based catalysts in catalyzing hydrogen production from chemical hydrides. Moreover, the synthesis methods, characterization techniques, and hydrogen production catalytic activity of Cu‐based catalysts were also introduced. Finally, a brief conclusion and outlook are given for the application of Cu‐based catalysts in the dehydrogenation of chemical hydrides. We hope that this review will stimulate interest in the promising research area of Cu‐based catalysts for the dehydrogenation of chemical hydrides.

“…In comparison, the catalytic capability of single metal Cu or Cu-based oxides is poor in some vitro catalytic reactions. 22 In order to solve this problem, structural modifications with introduction of other metals or metal oxides to Cu-based nanozymes could further reinforce the catalytic activity of Cu-based complexes. 23 Importantly, hybrid nanocomposites with the introduction of double-or multimetals stand out because of their featured electronic structures and synergistic effect.…”

With the improvement of the quality of life, the assessment of total antioxidant capacity (TAC) has attracted much attention in the field of a healthy diet, food analysis, or health guidelines. In this work, Cu nanoparticles (NPs)/CoO/carbon nanofibers (CNFs) as a promising nanozyme for peroxidase (POD) mimicking was synthesized by electrospinning and carbonation. Subsequently, a colorimetric sensing platform is constructed for TAC assessment by using 3,3′,5,5′-tetramethylbenzidine (TMB) as a chromogenic substrate based on Cu NPs/ CoO/CNFs under presence of H 2 O 2 . The enhanced POD catalytic efficiency of Cu NPs/CoO/CNFs for TMB oxidation (ox-TMB) was about 3.2-fold higher than that of bare Cu NPs/CNFs or CoO/NFs, which was ascribed to the synergistic catalytic effect and the generation of heterogeneous interfaces between Cu NPs and CoO in CNFs. When some antioxidants such as AA, FA, TA, and GA were introduced in the chromogenic system, ox-TMB was reduced to colorless TMB, allowing the subsequent assessment of TAC. The results show that the limits of detection toward AA, FA, TA, and GA were 8.7, 8.3, 2.7, and 2.4 μM, respectively. Moreover, this proposed method was used for the TAC assay in real samples including fresh juices and commercial beverages, which showed good promise in practical applications such as food nutrition assessment, food analysis, personalized nutrition intervention, or staple food research.

Recent Progress on Cobalt‐Based Heterogeneous Catalysts for Hydrogen Production from Ammonia Borane

Ammonia borane (NH3BH3, AB) is a quintessential exemplar of chemical hydrogen storage materials and has been widely used in hydrogen evolution. Although expensive metal catalysts (such as Rh, Ru, Pt, Ag, etc.) exhibit high activity in the hydrolysis of ammonia borane, inexpensive metals are more economical. Cobalt (Co), in particular, is not only relatively inexpensive and readily available, but also possesses high activity and selectivity. Compared to other catalysts, cobalt‐based catalysts have better durability and can maintain catalytic activity for a longer period of time, making them favored by researchers. These catalysts demonstrate excellent stability, hydrogen evolution rate, and turn over frequency. This article summarized previous progress in low price metal cobalt‐based catalysts for hydrogen precipitation from ammonia borane, focusing on cobalt‐based catalysts supported on various supports, especially those supported on carbon materials, metal oxides, MOFs, and nickel foams. The characteristics of high‐performance catalytic systems are analyzed in detail. The development prospects of Co catalysts for hydrogen production from ammonia borane were also discussed.
