Continuous-Flow Sunlight-Powered CO2 Methanation Catalyzed by y-AI2O3-Supported Plasmonic Ru Nanorods

Comparing the Performance of Supported Ru Nanocatalysts Prepared by Chemical Reduction of RuCl3 and Thermal Decomposition of Ru3(CO)12 in the Sunlight-Powered Sabatier Reaction

The preparation of Ru nanoparticles supported on γ-Al2O3 followed by chemical reduction using RuCl3 as a precursor is demonstrated, and their properties are compared to Ru nanoparticles supported on γ-Al2O3 prepared by impregnation of γ-Al2O3 with Ru3(CO)12 and subsequent thermal decomposition. The Ru nanoparticles resulting from chemical...

Renewable natural gas as climate-neutral energy carrier?

Natural gas is a potent greenhouse gas but remains an attractive energy resource for a good number of reasons. Because complementing the use of natural gas with carbon dioxide capture and storage yields several drawbacks, producing synthetic natural gas instead could be an interesting alternative. Methanation is an established and well-known...

Low temperature sunlight‐powered reduction of CO2 to CO using a plasmonic Au/TiO2 nanocatalyst

Sunlight-powered reduction of CO2to fuels and chemicals is apromising strategy to close the carbon loop and facilitate theenergy transition. In this research, we demonstrate that Aunanoparticles supported on TiO2are an efficient plasmoniccatalyst for the sunlight-powered reverse water-gas shift (rWGS)reaction. A maximum CO production rate of429...

Structural color coatings for high performance BIPV

Building integrated photovoltaics (BIPV) offer aesthetics and freedom of design for architects and home owners. This can accelerate implementation and free up new spaces for solar energy harvesting at building level, which is a necessary step towards a climate neutral built environment. Colored solar panels with high conversion efficiency and...

Collective photothermal effect of Al2O3-supported spheroidal plasmonic Ru nanoparticle catalysts in the sunlight-powered Sabatier reaction

Rheological response of a modified polyacrylamide-silica nanoparticles hybrid at high salinity and temperature

Water-soluble polyacrylamides have often been used to modify flow response in various water-based technologies and industrial processes, including paints, water treatment, paper manufacturing, and chemical enhanced oil recovery. Polymers are susceptible to degradation at combined high salinity and elevated temperature conditions which limits...

Suzuki-Miyaura Cross-Coupling Using Plasmonic Pd-Decorated Au Nanorods as Catalyst: A Study on the Contribution of Laser Illumination

The interaction between plasmonic metal catalysts and visible light can be exploited to increase their catalytic activity. This activity increase results from the generation of hot charge carriers or hot surfaces, or a combination of both. We have studied the light-induced Suzuki-Miyaura cross-coupling reaction of bromobenzene and m-tolylboronic...
