Dry reforming of methane, which converts two greenhouse gases to useful chemical feedstocks, has been regarded as a promising strategy to address global climate change and sustainable energy development. Design of effective nonnoble metal catalysts is key to achieving its industrial implementation. However, conventional Ni-based catalysts often suffer from deactivation by carbon coking and metal sintering, while complex catalyst synthesis approaches inevitably lead to high cost. This work presents a continuous, one-step, vapor-phase synthesis route to produce a highly stable Ni/ZrO2 nanoshell catalyst with excellent resistance to both coking and sintering. The methods proposed in this work are expected to expand routes to heterogeneous catalyst synthesis with impact on both scientific and industrial communities.

Hypoxia is one of the most important limiting factors in photodynamic therapy that can reduce the effectiveness of this treatment. By designing a nanocomplex of plasmonic nanoparticles and photosensitizers with similar optical properties, the rate of free oxygen radical production can be increased and the efficiency of photodynamic therapy can be improved. in this study, we tried to use the outstanding capacities of hollow gold nanoshells (HGNSs) as a plasmonic nanocarrier of methylene blue (MB) to improve the performance of photodynamic therapy.
