“…[1][2][3][4][5] It is also important that the starting acid can be produced with high yields from renewable biomass by hydrolysis of cellulose 6 or by its oxidation. 5,7 Additionally, formic acid can be used directly for hydrogenation reactions instead of molecular hydrogen, providing the advantage of easier transportation and storage of the hydrogenating agent.…”

Formic acid is a valuable chemical derived from biomass, as it has a high hydrogen-storage capacity and appears to be an attractive source of hydrogen for various applications. Hydrogen production via formic acid decomposition is often based on using supported catalysts with Pt-group metal nanoparticles. In the present paper, we show that the decomposition of the acid proceeds more rapidly on single metal atoms (by up to one order of magnitude). These atoms can be obtained by rather simple means through anchoring Pt-group metals onto mesoporous N-functionalized carbon nanofibers. A thorough evaluation of the structure of the active site by aberration-corrected scanning transmission electron microscopy (ac-STEM) in high-angle annular dark field (HAADF) mode, by CO chemisorption, X-ray photoelectron spectroscopy (XPS) and quantum-chemical calculations reveals that the metal atom is coordinated by a pair of pyridinic nitrogen atoms at the edge of graphene sheets. The chelate binding provides an ionic/electron-deficient state of these atoms prevents their aggregation and thereby leads to an excellent stability under the reaction conditions. Catalysts with single atoms have also shown very high selectivity. Evidently, the findings can be extended to hydrogen production from other chemicals and can be helpful for improving other energy-related and environmentally benign catalytic processes.

“…One issue that was raised by the authors however was the gradual loss of amine, required for high efficiencies, from the system. This represents a further challenge as without recycling of the amine the solution was seen to become progressively more acidic with the addition of further formic acid [45].…”

Recent years have seen an increasing demand for fossil-fuels and consequent mounting damage to the environment. With this increasing demand the need for a renewable alternative source of energy is required. Hydrogen has been highlighted as an interesting alternative energy carrier showing both practical and economic advantages, particularly when used in conjunction with a hydrogen fuel cell [1]. Whilst there has been much progression in the clean and renewable production of hydrogen through; biomass gasification, photoelectrolysis and also electrolysis using energy derived from renewable sources [2,3], a challenge remains for the storage and delivery of hydrogen for small and mobile applications. This mini-review discusses a range of viable C1 hydrogen storage materials and focuses on the key publications, as well as recent additions to the literature, related to the ruthenium catalysed release of hydrogen as this is one of most intensively researched areas of the field. Current progress in the homogeneous ruthenium catalysed reduction of CO2 is also discussed.

“…When combined with their reverse formic acid decomposition to release H 2 , they serve to help assess the feasibility of formic acid as liquid carrier for H 2 . 21 Novel catalysts for hydrogenation of carbonates to methanol are also emerging in the academic literature showing a further possible longer term approach. 22 Concurrent with these short-term PtL and PtG technologies via catalysed CO 2 hydrogenation reactions with renewable energy source, a major current industrial …”
