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.

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.

Noble metal (Cu, Ag, and Au) nanocluster catalysts and nano-crystalline photocatalytic cocatalysts have been prepared on a large scale (gram-scale) using a facile one-way strategy. The uniformly deposited Cu, Ag, and Au nanoclusters with controllable loading amount, size, and crystallization are efficient cocatalysts for organic synthesis, while the corresponding nanocrystals are efficient cocatalysts for enhanced hydrogen evolution. On a TiO2 support,the synthesized metal nanoclusters demonstrated enhanced catalytic organic synthesis of 4-aminophenol from 4-nitrophenol. The Au/TiO2 photocatalyst exhibited promising quantum efficiency. The higher sensitivity of the photocurrent response of the film photoelectrodes increases their versatility in photocatalyst applications.In addition to efficient cocatalyst preparation, the uniform loading ofnoble metal nanoclusters on TiO2 nanosheets achieved through our strategy provides a potential alternative to built-up metal nanocluster catalysts, as efficient performance is attained with low loading.

The excellent sodium storage properties of the NaTi2(PO4)3/reduced graphene oxide (rGO) nanocomposite could be attributed to the nano-sized NaTi2(PO4)3 particles, which significantly reduced the transport lengths for Na+ ions, and an intimate contact between the NaTi2(PO4)3 particles and rGO due to chemical bonding.

A synthesis strategy is developed to prepare oxygen evolution reaction (OER) catalysts based on the in situ decomposition of Co-based acetate hydroxide metal-organic frameworks (MOFs) at room temperature. The resulting Co-based hydroxides possess an interesting ultrathin nanosheet morphology with controllable com-position, and their electrocatalytic activity for the OER is superior to that of the state-of-the-art IrO2 electrocatalyst. This facile, cost-effective strategy opens a promising avenue for large-scale fabrication of functional nanocatalysts for use in clean energy technologies.
