Nitrogen‐rich and porous carbon materials have attracted great attention for supercapacitors due to the relatively large specific surface area, highly active N species and good electrical conductivity. However, it is still a challenge to precisely regulate the above characteristics simultaneously. Here artful sol‐gel‐assisted inorganic template methods are proposed by using melamine and polyethylene glycol (PEG) as complement and magnesium nitrate as inorganic salt to prepare nitrogen‐rich hierarchical porous carbon with three different pore structure (1.75 nm, 3.8 nm and 9.07 nm), giving the opportunity to regulate the specific surface area and pore size distribution of the carbon materials. The designer porous carbon possesses more than 9 at. % of the pyridinic nitrogen (N‐6) and pyrrolic nitrogen (N‐5), a high specific surface area of 917.0 m2 g−1 and good electrical conductivity (1.28 S cm−1). All these factors result in a specific capacitance up to 371 F g−1 at 1 A g−1 and excellent cycle stability (retain 98.3 % capacitance after 10000 cycles).

“…A series of mesoporous transition metal phosphates have been synthesized using the soft templating method, such as Ni, Sn, Ti, Fe, Mn and Co phosphates. [37][38][39][40][41][42] There exist many factors influencing the properties of final materials for the structure-directing strategy, such as the choice of surfactant and inorganic metal and phosphate precursors, the concentration of surfactant, the formation of surfactant micelle and the removal of template. (Co 3 (PO ) ) were synthesized through self-assembly of polymeric micelles consisting of triblock co-polymer (PS-PVP-PEO) (Figure 1a).…”

Over the past decade, transition metal phosphate materials have attracted enormous interest for various functional devices. In addition to being low‐cost, earth‐abundant and environmentally benign, transition metal phosphates have several unique advantages including high stability, unique chemical/physical characteristics and tunable multifunctionality, making them ideally suited for advanced highly‐efficiency energy conversion and storage applications. In this Review, the synthetic strategies for transition metal phosphates are summarized, and the most recent advances in the development of transition metal phosphates are described for efficient electrocatalysis such as oxygen evolution, hydrogen evolution and oxygen reduction reactions, highlighting the impact of their morphologies and structures on the electrochemical performance and practical applications in overall water splitting and rechargeable metal‐air batteries. Finally, the challenges facing the development of transition metal phosphates in the field of energy conversion and storage are outlined, together with directions of further research and perspectives.

“…In case of EDLC, the capacitance is generated from the accumulated electrostatic charge at the electrode/electrolyte interface, and the representative electrode materials are carbon materials such as activated carbon [119], carbon nanotubes (CNTs) and graphene (GN). For pseudocapacitors, the capacitance normally comes from the reversible faradic (redox) processes within various materials such as metal oxides [120,121], metal hydroxides and conducting polymers.…”

Recently, two-dimensional transition metal dichalcogenides, particularly WS 2 , raised extensive interest due to its extraordinary physicochemical properties. With the merits of low costs and prominent properties such as high anisotropy and distinct crystal structure, WS 2 is regarded as a competent substitute in the construction of next-generation environmentally benign energy storage and conversion devices. In this review, we begin with the fundamental studies of the structure, properties and preparation of WS 2 , followed by detailed discussions on the development of various WS 2 and WS 2-based composites for electrochemical energy storage and conversion applications. In the end, some prospective prospects and promising developments of WS 2 in these fields are proposed.
