Porous carbon fabrication techniques: A review

Iron–Cobalt Nanoparticles Embedded in B,N-Doped Chitosan-Derived Porous Carbon Aerogel for Overall Water Splitting

“…The bifunctional capability of the synthesized BNPC-FeCo-T electrocatalysts was based on their morphology and composition: (i) the 3D porous structure facilitated the diffusion and permeation of the reactant species, as well as the electron transfer during HER/OER, (ii) the porous carbon support effectively suppressed aggregation/agglomeration ensuring a homogeneous dispersion of the FeCo metal nanoparticles augmenting the catalyst’s activity, (iii) FeCo nanoparticles were shielded from the hostile alkaline environment by the carbon layer that was securely wrapped around them, which prevented leaching and corrosion during operation and promoted long-term stability, (iv) heteroatom doping with B and N created defects in the carbon structure that could also serve as active sites, especially Pyridinic-N species, which is beneficial for both HER and OER. Additionally, B and N codoping could modulate the electronic structure, enhancing the overall conductivity. , …”
