Special Issue Information

Dear Colleagues,

Nanoporous materials have a nanoscale pore size, which causes them to have a high specific surface area, excellent electrical conductivity, physical and chemical stability, gas–liquid permeability, a pore structure that can be regulated, and other advantages, so they show great application prospects in the fields of energy storage and conversion, catalysis, adsorption, and separation.

Porous carbon nanomaterials are commonly used as catalysts. Compared with traditional catalyst carriers, the pore structure is regular and controllable, and the connecting holes between the pores are small. A catalyst is restricted in pores after loading, and it is not easy to agglomerate, which significantly improves the catalyst’s life. The required pore structure can also be accurately designed according to the size of the reactants and products to facilitate the entry and exit of reactants and products, which can significantly improve catalytic efficiency. In addition, porous carbon can also be used as a nonmetallic catalyst, such as nitrogen-doped porous carbon materials, which have catalytic activity in many reactions, and its application in oxidation, electrocatalysis, and acetylene hydrochlorination has been widely examined.

This Special Issue aims to collect the most recent progress and new developments in the design, synthesis, and characterization of porous carbon nanomaterials, as well as their catalytic applications. In this Special Issue, original research articles and reviews are welcome.

We look forward to receiving your contributions.

Formic acid has emerged as a highly promising hydrogen storage material, and the development of efficient catalysts to facilitate its dehydrogenation remains imperative. In this study, a novel catalyst consisting of palladium nanoparticles supported on boron-doped porous carbon (Pd/BPC) was successfully synthesized to enable efficient hydrogen production through the dehydrogenation of formic acid. The impacts of the boron doping ratio, doping temperature, and palladium reduction temperature on the catalyst’s performance were systemically investigated. The results demonstrated the Pd/BPC catalyst synthesized with a carbon-to-boron ratio of 1:5 by calcination at 900 °C and subsequent reduction at 60 °C exhibited superior formic acid dehydrogenation performance, being 2.9 and 3.8 times greater than that of the Pd/PC catalysts without boron doping and commercial Pd/C, respectively. Additionally, the catalyst showed excellent cycle stability with no significant activity reduction after five consecutive cycles. Experimental and theoretical results reveal that boron doping not only facilitates the homogenous distribution of Pd nanoparticles but also induces a stronger support–metal interaction, thereby reinforcing the catalytic performance. This research is expected to provide valuable insights into the economically viable and efficient production of environmentally friendly hydrogen energy. Full article
