Formic acid (FA) is found to be a potential candidate for the storage of hydrogen. For dehydrogenation of FA, the supports of our catalysts were acquired by conducting ZnCl2 treatment and carbonation for biomass waste. The texture and surface properties significantly affected the size and dispersion of Pd and its interaction with the support so as to cause the superior catalytic performance of catalysts. Microporous carbon obtained by carbonization of ZnCl2 activated peanut shells (CPS-ZnCl2) possessing surface areas of 629 m2·g−1 and a micropore rate of 73.5%. For ZnCl2 activated melon seed (CMS-ZnCl2), the surface area and micropore rate increased to 1081 m2·g−1 and 80.0%, respectively. In addition, the introduction of ZnCl2 also caused the increase in surface O content and reduced the acidity of the catalyst. The results represented that CMS-ZnCl2 with uniform honeycomb morphology displayed the best properties, and the as-prepared Pd/CMS-ZnCl2 catalyst afforded 100% hydrogen selectivity as well as excellent catalytic activity with an initial high turnover number (TON) value of 28.3 at 30 °C and 100.1 at 60 °C.

Morphological Attributes

Abstract Although single-atom catalysts (SACs) have been widely employed in the CO2 reduction reaction (CO2RR), the understanding regarding the effect of morphological attributes on catalytic performance are still lacking, which prevents the rational design of high-performance catalysts for electrochemical CO2RR. Here, we developed a novel catalyst with axial Co-N5 sites embedded on controllable mesoporous carbon nanosphere with different graded pore structures. Benefiting from the precise control of porosity, the influence of morphological attributes on catalytic performance was well revealed. In situ characterization combined with density functional theory (DFT) calculations revealed that axial N-coordination induced local d-p orbitals coupling enhancement of Co with oxides and the optimal pore size of 27 nm promoted the interfacial bonding characteristics, which facilitate both the COOH* generation and CO desorption. Consequently, A superior selectivity of nearly 100% at -0.8 V vs. RHE and commercially relevant current densities of >150 mA cm−2 could be achieved, and a strikingly high turnover frequency of 1.136*104 h−1 at -1.0 V has been obtained, superior to the most of Co-based catalysts.

Great Focus

The production of H2 from the so-called Liquid Organic Hydrogen Carriers (LOHC) has recently received great focus as an auspicious option to conventional hydrogen storage technologies. Among them, formic acid, the simplest carboxylic acid, has recently emerged as one of the most promising candidates. Catalysts based on Pd nanoparticles are the most fruitfully investigated, and, more specifically, excellent results have been achieved with bimetallic PdAg-based catalytic systems. The enhancement displayed by PdAg catalysts as compared to the monometallic counterpart is ascribed to several effects, such as the formation of electron-rich Pd species or the increased resistance against CO-poisoning. Aside from the features of the metal active phases, the properties of the selected support also play an important role in determining the final catalytic performance. Among them, the use of carbon materials has resulted in great interest by virtue of their outstanding properties and versatility. In the present review, some of the most representative investigations dealing with the design of high-performance PdAg bimetallic heterogeneous catalysts are summarised, paying attention to the impact of the features of the support in the final ability of the catalysts towards the production of H2 from formic acid.
