In this review, we discuss the recent progress in the synthesis of two-dimensional (2D) transition metal dichalcogenides (TMDCs) and optoelectronic devices research. We also provide our perspectives on the opportunities they offer for future generations of nanophotonics technology.

A molecular co-catalyst is selectively photo-deposited at the apex of a visible-light-active semiconductor nanopyramid by utilizing the spontaneous photoelectric-field-enhancement effect for achieving enhanced photocurrent under solar illumination in neutral aqueous solutions as a result of the separation of anisotropic photogenerated charge carriers.

Using first-principles calculation, we systematically studied the strain effects on functionalized Si(111) thin films. By using strain and carrier doping, the systems can be tuned to form topological insulators or superconductors.

Pd-Ag alloy hollow nanostructures have been developed for application to the electrocatalytic formic acid oxidation reaction.When a certain amount of Ag atoms are incorporated into the Pd lattice, the electrocatalysts exhibit improved catalysis of formic acid oxidation. As indicated by first-principles simulations, the coupling between Pd and Ag induces polarization charges on the Pd catalytic sites, which can enhance the adsorption of HCOO* species onto Pd. This design represents a strategy for reducing the usage of expensive Pd while boosting electrocatalytic performance.

Double modification of MoSe2 nanosheets is realized in a C-MoSe2/reduced graphene oxide composite by introducing a graphene skeleton and an outer carbon protective layer via a facile one-step hydrothermal method. The designed C-MoSe2/rGO composite exhibits noticeably enhanced sodium ion storage, with a high capacity of 445 mAh·g−1 at 200 mA·g−1 after 350 cycles and superior rate performance, making it one of the most promising anode materials for sodium ion batteries.

Photodynamic therapy (PDT) with zinc phthalocyanine-encapsulating cationic liposomes results in tumor hypoxia due to intratumoral oxygen depletion, tumor cell death, and vascular shutdown. Tumor hypoxia leads to activation of hypoxia-inducible factor 1 (HIF-1),survival signaling, and reduced PDT efficacy. PDT outcome can be improved by the use of acriflavine, which inhibits HIF-1 and impairs survival signaling.
