“…In another attempt, a novel tube-like metal-carbon nanocomposite was introduced by Song et al with encapsulated Fe, Cr, and Ni nanoparticles via carbonization of the FeCr-doped Ni-benzenetricarboxylate aerogel. 156 The thin feature of the aerogel skeleton together with supercritical drying and Cr doping prevented the aggregation of the metal and promoted the in situ growth of carbon tubes. The fabricated electrocatalyst demonstrated an ultralow overpotential of 137 mV for HER and 220 mV for OER.…”

“…Song et al prepared the tube-like metal-carbon nanocomposite A-FeCrNi/C via the pyrolysis of the FeCr-doped NiBTC aerogel. 161 The FeCr-doped NiBTC aerogel has a 3D spongy-like network of aggregated nanoparticles, while A-FeCrNi/C consists of tangled and branched carbon tubes with highly dispersed encapsulated nanoparticles (10 nm). More active sites were exposed for the morphology, and diffusion paths were shortened for electrocatalysis so that A-FeCrNi/C achieved good OER activity with 10 mA cm −2 current density and only 220 mV overpotential, lower than commercial RuO 2 (280 mV) (Fig.…”

“…[66b] This procedure with several modifications is extensively used today for the preparation of metal-doped carbon gels. [67] Alternatively, metal-supported catalysts are obtained by classical methods -impregnation, CVD, etc. -using the previously optimized carbon supports and the appropriate active phases.…”
