“…Regarding doping, alloys, oxides, and nitrides of transition metal materials have been reported as abundant materials that exceed the electrolysis efficiency of noble metals during the OER. 9–12 Among them, transition metal nitrides showed superior OER electrocatalytic performance due to their high electrical conductivity, which is derived from their metallic properties. 13–15 To boost the electrocatalytic activity of transition metal based materials, numerous efforts have focused on modulating the electronic structure related to catalytic activity in the OER.…”

Research of electrocatalysts based on biomass derived porous carbon materials become one of promising strategies to boost the development of carbon cycle and energy storage technologies. As substitutes for precious metals in electrocatalysis, many biomass derived porous carbon materials exhibit excellent chemical stability, interface chemical inertness, strong structural mechanical strength and high conductivity. However, significant efforts are still needed to develop environmentally friendly, scalable and low‐cost synthetic methods to provide biomass‐derived carbonaceous materials with electrocatalytic performance that is comparable to, or even surpasses, that of existing precious metal catalysts. In this mini‐review, the main synthesis methods, electrocatalytic performances and working principle of biomass derived porous carbon materials have been summarized and discussed. The perspectives of doping strategy for these electrocatalyst candidates have been emphasized in the discussion.

Metal‐air secondary batteries with ultrahigh specific energies have received vast attention and are considered new promising energy storage. The slow redox reactions between oxygen‐water molecules lead to low energy efficiency (55–71%) and limited applications. Herein, it is proposed that the MIL‐68(In)‐derived porous carbon nanotube supports the CoNiFeP heteroconjugated alloy catalyst with an overboiling point electrolyte to achieve the ultrahigh oxidation rate of water molecules. Structural characterization and density functional theory calculations reveal that the new catalyst greatly reduces the free energy of the process, and the overboiling point further accelerates the dissociation of O─H and hydrogen bonds, and the release of O2 molecules, achieving an extra‐low overpotential of 110 mV@10 mA cm−2 far lower than commercial Ir/C catalysts of 192 mV at 125 °C and state‐of‐the‐art. Furthermore, the energy efficiency of assembled rechargeable zinc‐air batteries begins to break through at 85 °C, jumps at 100 °C, and reaches ultrahigh energy efficiency of 88.1% at 125 °C with an ultralow decay rate of 0.0068% after 150 cycles far superior to those of reported metal‐air batteries. This work provides a new catalyst and electrolyte joint‐design strategy and reexamines the battery operating temperature to construct higher energy efficiency for secondary fuel cells.
