A two-dimensional lateral transition metal disulfide-oxide-disulfide heterostructure with a configuration of an ultrathin Nb₂O₅ channel and two metallic NbS₂ electrodes is fabricated by a simple lithographyfree, laser-patterning technique. The heterostructure can be used as an ultrasensitive two-terminal sensor based on the modulation of Nb₂O₅ surface conduction through the naturally adsorbed water molecules.

Reaction environment self-modification on low-coordination Ni²⁺ octahedra atomic interface for superior electrocatalytic overall water splitting

Kaian Sun^1,2, Lei Zhao¹, Lingyou Zeng¹, Shoujie Liu², Houyu Zhu³, Yanpeng Li¹, Zheng Chen², Zewen Zhuang², Zhaoling Li⁴, Zhi Liu¹, Dongwei Cao³, Jinchong Zhao¹, Yunqi Liu¹ (✉), Yuan Pan¹ (✉), and Chen Chen² (✉)

A novel coordination environment inheriting strategy was developed for the synthesis of low-coordination Ni²⁺ octahedra atomic interface. Advanced spectroscopic techniques and theoretical calculations reveal that the self-matching electron delocalization and localization state at the bifunctional active sites L-Ni-8 enables an ideal reaction environment at both cathode and anode. To improve the efficiency of using the self-modification reaction environment at L-Ni-8, all of the structural features from atomic-scale to macro-scale are integrated together to drive superior overall water splitting performance at high current density.

Yongye Liang^§, Hailiang Wang^§, Hernan Sanchez Casalongue, Zhuo Chen, and Hongjie Dai ()

A graphene/TiO₂ nanocrystals hybrid has been prepared by directly growing TiO₂ nanocrystals on graphene oxide (GO) sheets by a two-step method, in which TiO₂ was first coated on GO sheets by hydrolysis and subsequently crystallized into anatase nanocrystals by hydrothermal treatment. The graphene/TiO₂ nanocrystals hybrid shows superior photocatalytic activity to other TiO₂ materials in the degradation of rhodamine B, with an impressive three-fold photocatalytic enhancement over P25
