“… 21 Bulushev et al prepared Ni/C single-atom catalysts; the conversion rate of FA was 40% at 350 °C, and the hydrogen selectivity was 95–97%. 59 The conversion rate of FA was significantly lower than the results in this paper, which may be due to the low active metal content for the single-atom catalyst. Compared with the above catalysts, the Ni10Mo1/PB catalyst in this paper exhibited an excellent catalytic performance.…”

Formic acid (FA), as a safe and renewable liquid hydrogen storage material, has attracted extensive attention. In this paper, a series of Mo-modified pseudoboehmite supported Ni catalysts were developed and evaluated for efficient hydrogen production from formic acid. Pseudoboehmite (PB) as a catalyst carrier was used for the first time. Ni/PB and NiMo/PB possessed a mesostructure, and the pore size distribution was mainly concentrated between 2 and 20 nm. The oxygen vacancies caused by Mo enhanced Ni anchoring, thus inhibiting Ni sintering. Compared with Ni10/PB (7.62 nm), Ni10Mo1/PB had smaller Ni particles (5.08 nm). The Ni–O–Al solid solutions formed through the interaction of Ni with the PB improved the catalytic performance. Ni10Mo1/PB gave the highest conversion of 92.8% with a H 2 selectivity of 98% at 300 °C, and the catalyst activity hardly decreased during the 50 h stability test. In short, Ni10Mo1/PB was a promising catalyst for hydrogen production from formic acid because of the oxygen vacancy anchoring effect as well as the formation of Ni–O–Al solid solutions which could effectively suppress the Ni sintering.

“…Highly stabilised and isolated single-atom Ni has been proven by HAADF-STEM findings (Figure 4A,B). Notably, both catalysts exhibited a superior transformation of formic acid into hydrogen (Figure 4C) [62], in which the reaction is predominated by 1Ni/CN as a result from the strong Ni atoms-N-species interaction on the carbon support (See XPS result, Figure 4D). Cheng et al also successfully synthesised a single cobalt atom anchored to N-doped carbon nanofibers (CNFs) [63].…”

Single-Atom Catalysts: A Review of Synthesis Strategies and Their Potential for Biofuel Production

et al. 2021

Biofuels have been derived from various feedstocks by using thermochemical or biochemical procedures. In order to synthesise liquid and gas biofuel efficiently, single-atom catalysts (SACs) and single-atom alloys (SAAs) have been used in the reaction to promote it. SACs are made up of single metal atoms that are anchored or confined to a suitable support to keep them stable, while SAAs are materials generated by bi- and multi-metallic complexes, where one of these metals is atomically distributed in such a material. The structure of SACs and SAAs influences their catalytic performance. The challenge to practically using SACs in biofuel production is to design SACs and SAAs that are stable and able to operate efficiently during reaction. Hence, the present study reviews the system and configuration of SACs and SAAs, stabilisation strategies such as mutual metal support interaction and geometric coordination, and the synthesis strategies. This paper aims to provide useful and informative knowledge about the current synthesis strategies of SACs and SAAs for future development in the field of biofuel production.

“…2,3 Among them, hydrogen (H 2 ) has been deemed as the most potential alternative for traditional fossil fuels because of its ultrahigh energy density (142 kJ g −1 ), [4][5][6][7] Earth abundance and environmental benefits. [8][9][10][11][12] However, safe production remains a barrier, and controllable storage and safe delivery of H 2 are needed for practical and portable applications. [13][14][15] Formic acid (FA), with a volumetric and gravimetric hydrogen content of 53.4 g L −1 and 4.4 wt%, has recently been considered as one of the most promising hydrogen carriers due to its abundance, non-corrosiveness, non-toxicity, and non-flammability.…”
