“…However, most metal oxides have the poor conductivity, which hinders the transport of charge carries and results in low OER efficiency. To improve conductivity of whole electrodes and facilitate the transfer of charge carries, most transition metal‐based compounds were composited with conductive substrates such as MoS 2 , black phosphorus, and conductive carbonaceous material . However, the electrochemical performance is usually not improved distinctly via such a composition strategy due to that the interfacial resistances between substrate and active materials are still large.…”

Combining transition metal oxide catalysts with conductive carbonaceous material is a feasible way to improve the conductivity. However, the electrocatalytic performance is usually not distinctly improved because the interfacial resistance between metal oxides and carbon is still large and thereby hinders the charge transport in catalysis. Herein, the conductive interface between poorly conductive NiO nanoparticles and semi-conductive carbon nitride (CN) is constructed. The NiO/CN exhibits much-enhanced oxygen evolution reaction (OER) performance than corresponding NiO and CN in electrolytes of KOH solution and phosphate buffer saline, which is also remarkably superior over NiO/C, commercial RuO 2 , and mostly reported NiO-based catalysts. X-ray photoelectron spectroscopy and extended X-ray absorption fine structure spectrum reveal that a metallic Ni-N bond is formed between NiO and CN. Density functional theory calculations suggest that NiO and CN linked by a Ni-N bond possess a low Gibbs energy for OER intermediate adsorptions, which not only improves the transfer of charge but also promotes the transmission of mass in OER. The metal-nitrogen bonded conductive and highly active interface pervasively exists between CN and other transition metal oxides including Co 3 O 4 , CuO, and Fe 2 O 3 , making it promising as an inexpensive catalyst for efficient water splitting.

“…The idea of employing electron donation from BP to electroactive material as discussed in the HER section was also studied for OER, for example, for systems Co(OH) 2 /BP, Co 3 O 4 @BP, Co/BP, BP/Co 2 P . Particularly, apart from the advantages of the electron dotation mechanism, Yu et al.…”

Phosphorene, generally defined as two-dimensional (2D) black phosphorus (BP) with monolayered or few-layered structure, has emerged as ap romising member of the family of 2D materials.S ince its discoveryi n2 014, extensive research has been focusedo nb roadening its applications, covering the biological, photoelectric, and electrochemical fields, owing to the unique physicochemical ands tructural properties. As as ingle-elemental material, phosphorene has demonstrated its applicability for the preparation of efficient electrocatalysts for hydrogen evolution reaction( HER), oxygen evolutionr eaction (OER), nitrogen reduction reaction (NRR), and other electrocatalytic applications. In this Minireview,asummary of the very recent research progresses of phosphorene in electrocatalysis is offered, with as pecial focus on the effective synthetic strategies towards performance improvement. In the concluding section, challenges and perspectives are also discussed. Figure 5. ORR performance of M-TLBP and M-CB in 0.1 m KOH.

“…[58] Soon after, cobalt hydroxide Co(OH) 2 /BP was designed as hybrid electrocatalysts to produce conductive CoÀ P bonds and promoted electrons transfer for OER. [75] Recently, theoretical simulations have found that tuning the local oxidation degree could effectively modulate the adsorption of reactive intermediates and thus improve the poor OER activity of pristine BP (Figure 3c). [76] Besides, foreign element doping and rational interface engineering could also serve as efficient methods to enhance the electrocatalytic performance of BP.…”

Hydrogen from electrocatalytic water splitting is a clean and renewable source of sustainable energy. Highly efficient electrocatalyst is of great importance for the low‐cost and large‐scale production of hydrogen. Effective electrocatalysts made of earth abundant elements such as element P have attracted extensive interest. Due to the attractive properties of black phosphorus (BP) including tunable physicochemical characteristics, unique in‐plane anisotropic structure, high charge‐carrier mobility, and large specific surface area, make it stand out from four allotropes. And the breakthrough in BP exfoliation enables it to be a promising 2D platform for designing flexible and versatile BP‐based materials. This review summarizes all these bulk BP, BP nanosheets, BP quantum dots (QDs) as well as BP‐based materials as efficient electrocatalysts in the last several years, with their synthesis methods and electrocatalytic properties for water splitting. Furthermore, some challenges and perspectives for the future development of BP‐based electrocatalysts have been briefly offered.
