| 1 | Nickel cobalt phosphide with three-dimensional nanostructure as al highly efficient electrocatalyst for hydrogen evolution reaction in both I acidic and alkaline electrolytes显示文摘Transition metal phosphides (TMPs) are promising candidates for noble metal free electrocatalysts in water splitting applicati ons. In this work, we prese nt the facile syn thesis of nickel cobalt phosphide electrocatalyst with three-dime nsional nano structure (3D-NiCoP) on the nickel foam, via hydrothermal reaction and phosphorization. The as-prepared electrocatalyst exhibits an excellent activity for hydrogen evolution reaction (HER) in both acidic and alkaline electrolytes, with small overpotentials to drive 10 mA/cm^2 (80 mV for 0.5 M H2SO4, 105 mV for 1 M KOH), small Tafel slopes (37 mV/dec for 0.5 M H2SO4, 79 mV/dec for 1 M KOH), and satisfying durability in long-term electrolysis. 3D-NiCoP also shows a superior HER activity compared to single metal phosphide, such as cobalt phosphide and nickel phosphide. The outstanding performa nee for HER suggests the great pote ntial of 3D-NiCoP as a highly efficient electrocatalyst for water splitting technology. | Bo Ma Zhengchun Yang Yantao Chen Zhihao Yuan | 2019 | Nano Research2019,12,2: | 14 |

| 3 | Cobalt phosphide nanoarrays with crystalline-amorphous hybrid phase for hydrogen production in universal-pH显示文摘To accomplish mass hydrogen production by electrochemical water-splitting,it is a necessary to develop robust,highly active,stable,and cost-effective hydrogen evolution reaction(HER)electrocatalysts that perform comparably to Pt in the universal pH range.In this work,cobalt phosphide hybrid nanosheets supported on carbon felt(CoP HNS/CF)are presented,which exhibit the superior electrocatalytic hydrogen production under a universal-pH.In these nanosheets,a single CoP HNS is composed of polycrystalline CoP and oxygen-enriched amorphous Co-O-P phase.Benefiting from its unique nanoarchitecture,as-fabricated CoP HNS/CF exhibits a tremendous electrocatalytic HER activity and outperforms Pt/C as well as state-of-the-art CoP electrocatalysts in universal-pH.In acidic and neutral media,the CoP HNS/CF shows superior electrocatalytic activity while maintaining its original hybrid crystalline-amorphous phase and morphology.In alkaline medium,the unexpected phase and morphological reorganization of CoP HNS/CF results in outstanding electrocatalytic operation.CoP HNS/CF not only achieves high electrocatalytic activity and kinetics,but also a stable and long operating lifetime even under a high current density of 500 mA cm'2.Furthermore,the fabrication of CoP HNS/CF can be scaled up easily,and the large CoP HNS/CF electrode also exhibits similar electrocatalytic activity and stability. | Hyunseok Yoon Hee Jo Song Bobae Ju Dong-Wan Kim | 2020 | Nano Research2020,13,9: | 4 |

| 6 | Boosting pH-Universal Hydrogen Evolution of Molybdenum Disulfide Particles by Interfacial Engineering显示文摘The design of high-efficiency non-noble and earth-abundant electrocatalysts for hydrogen evolution reaction(HER)is highly paramount for water splitting and renewable energy systems.Molybdenum disulfide(MoS_(2))with abundant edge sites can be utilized as a promising alternative,but its catalytic activity is greatly related to the pH values,especially in an alkaline environment due to the extremely high energy barriers for water adsorption and dissociation steps.Here we report an exceptionally efficient and stable electrocatalyst to improve the sluggish HER process of layered MoS_(2)particles in different pH electrolytes,especially in base.The electrocatalyst is constructed by in situ growing selenium-doped MoS_(2)(Se-MoS_(2))nanoparticles on three-dimensional cobalt nickel diselenide(mCo_(0.2)Ni_(0.8)Se_(2))nanostructured arrays.Due to the large number of active edge sites of Se-MoS_(2)particles exposed at the surface,robust electrical conductivity and large surface area of mCo_(0.2)Ni_(0.8)Se_(2)support,and strong interfacial interactions between Se-MoS_(2)and mCo_(0.2)Ni_(0.8)Se_(2),this hybrid catalyst shows very outstanding catalytic HER properties featured by low overpotentials of 30 and 122 mV at 10 and 100 mA/cm^(2)with good operational stability in base,respectively,which outperforms most of inexpensive catalysts consisting of layered MoS_(2),transition metal selenides and sulfides,and it performs as well as noble Pt catalysts.Meanwhile,this electrocatalyst is also very active in neutral and acidic electrolytes,requiring low overpotentials of 93 and 94 mV at 10 mA/cm^(2),respectively,demonstrating its superb pH universality as a HER electrocatalyst with excellent catalytic durability.This study provides a straightforward strategy to construct an efficient non-noble electrocatalyst for driving the HER kinetics in different electrolytes. | Liling Liao Lun Yang Gang Zhao Haiqing Zhou Fengming Cai Yi Li Xiuzhang Wang Fang Yu | 2021 | Chinese Journal of Chemistry2021,39,2: | 2 |
