“…Simultaneous doping with B and N significantly reduces the adsorption energy of the hydrogen intermediate at Ru sites, which enhances the HER kinetics . S-doped (Tavakol et al, 2020) or P-doped (Song et al, 2022) CNTs have also shown potential in improving HER kinetics.…”

Electrocatalytic materials are pivotal for clean chemical production and energy conversion in devices like electrolyzers and fuel cells. These materials usually consist of metallic nanoparticles which serve as active reaction sites, and support materials which provide high surface area, conductivity and stability. When designing novel electrocatalytic composites, the focus is often on the metallic sites, however, the significance of the support should not be overlooked. Carbon materials, valued for their conductivity and large surface area, are commonly used as support in benchmark electrocatalysts. However, using alternative support materials instead of carbon can be beneficial in certain cases. In this minireview, we summarize recent advancements and key directions in developing novel supports for electrocatalysis, encompassing both carbon and non-carbon materials.

“…[43,44] Moreover, in the case of metal decoration, heteroatom doping increases the ability of carbon material to adsorb and keep nanoparticles on their surfaces. [45,46] Therefore, after the completion of some successful studies related to the synthesis and catalytic applications of carbon-based materials by this group, [47][48][49][50] and because the importance of these catalytic systems for the reduction of various functional groups [51][52][53] an attempt was made to use these materials as support of nickel catalyst for the conversion of nitrobenzenes to the related aniline derivatives. Since the high polarizability of phosphorus atom greatly enhances its noncovalent interaction with metals, P-doped carbon materials are one of the most useful candidates for metal decoration.…”

Phosphorus-modified porous carbon (PCP) with about 7 w% phosphorus content has been prepared from acetylene and triphenylphosphine using chemical vapor deposition method. Then,5,10,15,20,25,and 30 w% nickel(0) nanoparticles have been deposited (using the in-situ reduction of NiCl2 salt) on the surface of PCP to obtain Ni-decorated PCP (NPCP). The prepared materials (NPCP) have been employed as a catalyst for the catalytic reduction of nitrobenzene derivatives to anilines. The NPCP with 20 w% of Ni showed the highest catalytic efficiency. The reaction was carried out using 10 mg catalyst, 2 mL of 25 % hydrazine hydrate solution as the reducing agent in 2 h (optimized conditions) to obtain the product in 51-100 % yield. To show the versatility of this method, 8 nitrobenzene derivatives (including 3 different nitrophenols) have been successfully reduced using this method. The recyclability of the catalyst was investigated and the results showed only 20 % decreasing in the yield after 6 runs.

“…They showed Zn and Co ferrites could not perform the desired product in 700 °C and led to spherical carbons. In this work, based on the work of Dhand and the previous experiences of this group on the sulfur doping and decoration of carbon nanostructures [29][30][31], sulfur-doped nanofibers (SCNFs) have been synthesized via the CVD method and decorated with gold nanoparticles (GNPs) by electrodeposition. This doping has been considered because of the strong interaction between sulfur and gold and its intense effects on carbon materials (based on our previous studies).…”

Sulfur-doped carbon nanofibers (SCNFs) were prepared using chemical vapor deposition. In this line, different catalysts and various growth temperatures have been examined to obtain the optimized conditions. Among the employed catalysts, NiFe 2 O 4 showed the most performance, and the best quality of the prepared SCNFs was 600 °C. To enhance the electrochemical behaviors, the prepared SCNFs was decorated with gold nanoparticles using electrochemical deposition. Both products (doped and undoped) were fully characterized using common methods. Then, they used for the electrochemical detection of morphine using cyclic voltammetry and square wave voltammetry. The obtained electrochemical diagrams demonstrated the high efficiency of the synthesized product for sensing of morphine.
