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.

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.
