Anatase TiO(2) single crystals with a large percentage of reactive facets
Hua Gui Yang,Chenghua Sun,Shi-Zhang Qiao,Jin Zou,Gang Liu,Sean C. Smith,Hui-Ming Cheng,Gao Qing Lu +7 more
TL;DR: This work synthesized uniform anatase TiO2 single crystals with a high percentage (47 per cent) of {001} facets using hydrofluoric acid as a morphology controlling agent and demonstrates that for fluorine-terminated surfaces this relative stability is reversed.
Unique Electronic Structure Induced High Photoreactivity of Sulfur-Doped Graphitic C3N4
TL;DR: The homogeneous substitution of sulfur for lattice nitrogen and a concomitant quantum confinement effect are identified as the cause of this unique electronic structure and the excellent photoreactivity of C(3)N(4-x)S(x), which may shed light on general doping strategies for designing potentially efficient photocatalysts.

Solvothermal synthesis and photoreactivity of anatase TiO(2) nanosheets with dominant {001} facets.
Hua Gui Yang,Gang Liu,Shi-Zhang Qiao,Chenghua Sun,Yong Gang Jin,Sean C. Smith,Jin Zou,Hui-Ming Cheng,Gao Qing Max Lu +8 more
TL;DR: The addition of 2-propanol can strengthen the stabilization effect associated with fluorine adsorption over (001) surface and thus stimulate its preferred growth, and the as-prepared anatase TiO(2) single-crystal nanosheets having 64% {001} facets show superior photoreactivity compared to P25 as a benchmarking material.

Nanoporous Graphitic-C3N4@Carbon Metal-Free Electrocatalysts for Highly Efficient Oxygen Reduction
Yao Zheng,Yan Jiao,Jun Chen,Jian Liu,Ji Liang,Aijun Du,Weimin Zhang,Zhonghua Zhu,Sean C. Smith,Mietek Jaroniec,Gao Qing Max Lu,Shi-Zhang Qiao +11 more
TL;DR: The proposed synthesis route is facile and low-cost, providing a feasible method for the development of highly efficient electrocatalysts, and demonstrated significantly higher catalytic efficiency than a Pt/C catalyst.

Isolated Diatomic Ni-Fe Metal-Nitrogen Sites for Synergistic Electroreduction of CO2.
TL;DR: Density functional theory studies reveal that the neighboring Ni-Fe centers not only function in synergy to decrease the reaction barrier for the formation of COOH* and desorption of CO, but also undergo distinct structural evolution into a CO-adsorbed moiety upon CO2 uptake.
