“…Hollow and porous nanostructures hold great potential for electrocatalysis, owing to their unique structural features, including more exposed active sites, lower mass density, and more efficacious mass transport compared to their solid counterparts. [ 93 ] For instance, porous/hollow CoP nanospheres [ 93 ] and CoNiP microspheres, [ 94 ] FeP nanosheets, [ 95 ] and Ni 2– x Cu x P nanosheets, [ 96 ] etc. have been successfully prepared.…”

“…MOFs are among the most versatile precursors/templates to fabricate various porous nanomaterials by thermolysis owing to their high surface area, abundant and tunable pore structure, and controllable morphologies. Co‐Fe MOF, [ 77,132 ] Co‐Ni MOF, [ 78,94 ] and their multimetal‐MOF analogues have been prepared via hydrothermal route or electrodeposition [ 138 ] as the precursors. The metal phosphides are then formed by pyrolysis and phosphorization.…”

their efficiencies, the catalysts employed are basically required to overcome the high energy barriers and sluggish kinetics of the electrochemical HER, OER, and ORR. [3] The benchmarking catalysts for ORR and HER are platinum (Pt)-based noble metal catalysts, whereas iridium (Ir) and ruthenium (Ru) oxides are highly active toward the OER. [4] Nevertheless, the high cost and scarcity of these precious metal-based catalysts have notably hindered their wide applications and commercialization. [5] Therefore, developing highly active, low cost, and sustained catalysts for these key electrocatalytic processes is paramount and apparently rewarding for the sustainable and large-scale implementation of clean energy devices. [6] To reduce, and hopefully to eliminate the usage of these precious metal-based catalysts, there have been intensive researches, in order to develop the practically and economically viable alternative electrocatalysts. [7] In this connection, phosphorus (P) is one of the most earth-abundant elements, thereby P-based materials have been considered being employed for electrocatalysis. [8] Indeed, P-based inorganic materials, especially the black phosphorus, metal phosphides, and metal phosphates, have attracted immense attention recently as a class of promising electrocatalysts, and presented intrinsic electrochemical activity and widely tunable properties. [9] Black phosphorus (BP) is a layer-structured semiconductor, in which individual atomic layers are stacked and held together by van der Waals interactions. [10,11] Until recently, BP stands out as a group of promising catalysts that have been investigated and shown to exhibit catalytic activities, owing to their unique puckered layer-structure, tunable band gap, and high carrier mobility. [12,13] As suggested by recent researches, 2D catalysts with reduced layer numbers or the thickness can present increased surface area and hence expose additional active sites, in comparison with their bulk counterparts. [14] To this end, phosphorene, as the building block for BP, possesses a monolayer (or a few layer) sheet structure, and has been explored for electrocatalysis and expected to promote the catalytic efficiency. [15,16] Nevertheless, because of the densely packed lone-pair p-electrons of phosphorus atoms, it would be hard for phosphorene to adsorb hydrogen, leading to the large hydrogen adsorption energy, and thus poor HER electrocatalytic Enormous progresses have been made in developing advanced energy conversion and storage technologies, which inevitably require high-performance electrocatalysts. Recently, phosphorus (P)-based materials have drawn tremendous attention as a class of promising electrocatalysts and presented intrinsic electrochemical activity and widely tunable property. In a timely response to the ongoing interests, issues faced in P-based inorganic materials, and the approaches to address them in relation to energy conversion reactions, including hydrogen evolution reaction, oxygen evolution reaction, and oxygen reduction reactio...

“…2(a)), the peaks at 207.6 and 210.3 eV are assigned to Nb 5+ 3d5/2 and Nb 5+ 3d3/2 of Nb2O5, respectively, which is due to the oxidation on the catalyst surface. The peaks at 207.1 and 203.6 eV are derived from Nb 4+ 3d3/2 and Nb 4+ 3d5/2 [29]. Furthermore, the S 2p1/2 signal at 163 eV indicates that the sample surface contains some S 2  , confirming the formation of a metal-sulfide phase.…”

Hollow multishelled structures (HoMSs) have gained numerous achievements in broad scientific research fields. In the past decade, the rapid developments of synthetic methods and advanced characterization technologies have enriched HoMS family with abundant chemical compositions and geometric structures. In addition, the control in phase structure and surface structure of HoMSs have also been reported in recent years. With great efforts devoted to controlling the compositional and structural characteristics, such as shell composition, shell number, shell thickness, and intershell space, HoMSs have displayed their intrinsic temporal–spatial nature and proven to be fruitful in optimizing mass transport, storage, and release. This review first summarizes the compositional and structural control of HoMSs in three levels, that is, building subunits, assembled functional shells, and HoMSs. Subsequentially, the essential influence of composition and structure on mass transport, storage, and release is deeply discussed by highlighting the application of HoMSs in energy storage, catalysis, electromagnetic wave absorption, and drug delivery. Finally, the challenges and opportunities in the future development of HoMSs are forecasted.
