“…The Pt nanoparticles exhibit uniform dispersion in CMK‐3 mesoporous structure without severe agglomeration. Hence, bring better ECSA (44.7 m 2 g −1 Pt ) when hybrid Pt‐CMK‐3 with commercial Pt‐CB compared to the commercial Pt‐CB (27.4 m 2 g −1 Pt ) [48] . It is worth noting that this ECSA is still lower than the catalyst supported by finer carbon black Vulcan XC‐72, which can reach 98.9 m 2 g −1 Pt [250] .…”

“…The so‐called hard template in this synthesis strategy plays a similar role as molds in metal casting. Silica, [46–51] polymer beads, [52–56] metal oxide [57–60] and zeolite [61–63] are the most widely used templates. A typical hard template assisting synthesis process usually involves the following steps: as presented in Figure 2a, mesoporous solid phases or colloidal crystals are first prepared as sacrificial molds.…”

“…The high specific surface area, highly controllable porous structure, and easy to modify surface enable mesoporous carbon excellent candidate for developing durable low‐Pt catalyst and noble‐metal‐free catalysts. Mesoporous carbons have been widely investigated as catalyst support for reducing the Pt loading and enhance the durability of the current Pt/C catalyst [48,247–251] . Moreover, many non‐precious metal fuel cell catalysts based on mesoporous carbon have also been synthesized and applied in PEMFC [40,61,252–257] …”

To meet the high‐speed commercialization demands of electrochemical energy storage and conversion devices, the development of high‐performance and low‐cost electrode materials is urgently necessary. Mesoporous carbon, which shows excellent intrinsic characteristics and flexible structure, has raised a surge of interest recently since it offers opportunities for improving the energy or power density and durability as well as reducing the cost of electrodes. In this paper, we first review primary methods for preparing mesoporous carbons. Next, the obstacles in lithium batteries, supercapacitors, proton exchange membrane fuel cells and water electrolyzers are analyzed and the recent progresses of mesoporous carbon based electrode designs in solving these obstacles are systematically introduced. Finally, we outline current challenges and future directions of developing mesoporous carbon based electrode materials in electrochemical energy storage and conversion devices. In creating this review, we hope to give a succinct introduction to the mesoporous carbon and provide meaningful references for its future research.
