“…Sun et al . prepared Sb 2 S 3 film on conductive FTO glass via a hydrothermal procedure with post-annealing treatment, which can be directly used as CE for DSCs [60] . Electrochemical characterizations demonstrated that the as-prepared Sb 2 S 3 film exhibited promising electrocatalytic activity and stability for catalyzing the triiodide reduction.…”

“…The first semicircle, located in the high-frequency region, is closely related with the charge-transfer resistance (Rct) at the CE/electrolyte interface. The value of Rct reflects the electrocatalytic activity of the counter electrode . The left intercept on the real axis in the plots reveals the ohmic series resistance (Rs), which is related to the conductivity of CEs.…”

One-dimensional single-crystal nanostructural nickel selenides were successfully in situ grown on metal nickel foils by two simple one-step solvothermal methods, which formed NiSe/Ni counter electrodes (CEs) for dye-sensitized solar cells (DSSCs). The nickel foil acted as the nickel source in the reaction process, a supporting substrate, and an electron transport "speedway". Electrochemical testing indicated that the top 1D single-crystal NiSe exhibited prominent electrocatalytic activity for I reduction. Due to the metallic conductivity of Ni substrate and the outstanding electrocatalytic activity of single-crystal NiSe, the DSSC based on a NiSe/Ni CE exhibited higher fill factor (FF) and larger short-circuit current density (J) than the DSSC based on Pt/FTO CE. The corresponding power conversion efficiency (6.75%) outperformed that of the latter (6.18%). Moreover, the NiSe/Ni CEs also showed excellent electrochemical stability in the I/I redox electrolyte. These findings indicated that single-crystal NiSe in situ grown on Ni substrate was a potential candidate to replace Pt/TCO as a cheap and highly efficient counter electrode of DSSC.

“…To advance catalytic performances, as one common strategy, extensive efforts are devoted to downsizing the catalysts to nanoscale in order to expose more active sites . However, it remains a noteworthy challenge because the tiny transitional metal‐based catalysts possessing high surface free energy intend to migrate and aggregate to grow up . To break the deadlock, carbon materials have been widely utilized as supporters to coordinate single transitional metal atoms, or anchor (or enwrap) transitional metal nanoparticles, transitional metal alloys, transitional metal compounds, etc .…”

The carbons containing metals coordinated with nitrogen are emerging as the most promising catalysts toward various heterogeneous catalyses. In this paper, such a carbon catalyst is prepared through a chemical vapor deposition (CVD)‐supported precursor pyrolysis. Compared with the direct pyrolysis of polypyrrole@cobalt salt precursor, the incorporation of dicyanodiamide as the CVD source facilitates the diversification and hierarchization of carbon morphology, the reduction of Co particle size, and the increase of the proportion of interfacial Co−N−C and pyridinic‐N. The catalyst is composed of in‐situ‐grown multiple‐morphology carbons (MMCs) with metallic Co particles embedded, where the MMCs are a combination of nano‐particles, ‐rods, and ‐wires, all comprised by small N‐doped carbon nanoflakes. Owing to the combined modulation on morphology configurations and defect states, the Co/MMCs catalyst demonstrates excellent activities toward hydrogen evolution reaction (HER), oxygen evolution reaction (OER), and oxygen reduction reaction (ORR). A half‐wave potential of 0.84 V and low overpotentials of 86 and 180 mV at 10 mA cm−2 current density for HER and OER are achieved, respectively. Additionally, the catalyst also demonstrates favorable prospects for large‐scale applications in overall water splitting and Zn‐air battery.
