In this work, we report a new synthesis method to prepare a Cu nanowire electrocatalyst for selective CO2 reduction at room temperature and atmospheric pressure. Cu nanowire array electrodes were prepared through a two-step synthesis of Cu(OH)2 and CuO nanowire arrays on Cu foil substrates and a subsequent electrochemical reduction of the CuO nanowire arrays. The Cu nanowire arrays are able to ...

malaysia, as a small and developing country, must reduce carbon emissions because the country is one of the top co2-emitting countries in the asean region. therefore, the current study implements two environmental tax policies; carbon and energy taxes, in order to examine the impacts of these policies on the reduction of carbon emission in the whole of the economy by applying a computable gener...

Conversion of the greenhouse gas carbon dioxide (CO2) to value-added products is an important challenge for sustainable energy research, and nanomaterials offer a broad class of heterogeneous catalysts for such transformations. Here we report a molecular surface functionalization approach to tuning gold nanoparticle (Au NP) electrocatalysts for reduction of CO2 to CO. The N-heterocyclic (NHC) c...

Aircraft operations have a significant impact on local air quality, climate change, fuel consumption and noise around airports. In order to reach emission targets set by aviation agencies (e.g. ACARE), to reduce environmental impact and to ensure a sustainable future of the sector, the aviation industry is continuously investing in research and development of technologies for reducing CO2, nois...

Application of price mechanisms has been the important instrument for carbon reduction, among which the carbon tax have been frequently advocated as a cost-effective economic tool. This study aims to assess the effects of carbon taxes on different industry sectors in Taiwan. A fuzzy goal programming approach, integrated with grey prediction and input-output theory, is used to construct a model ...

China has become the world’s largest carbon dioxide (CO2) emitter. Sectoral production activities promote economic development while also adding considerably to national CO2 emissions. Due to their different sectoral structures, each region shows different levels of economic development and CO2 emissions. The Chinese government hopes to achieve the dual objectives of economic growth and CO2 emi...

The extensive and close economic linkages among different regions of China have effects not only on regional economic growth, but also on CO2 emissions and carbon leakage among regions. Taking Beijing as a study case, we constructed MRIO models for China’s 30 provinces and municipalities for 2002, 2007 and 2010, to measure the embodied CO2 emissions in the interregional trade of China on region...

The effects of pressure and temperature on the energy (Eop) of the metal-to-metal charge transfer (MMCT, FeII-->CoIII) transition of the cyano-bridged complexes trans-[L14CoNCFe(CN)5]- and cis-[L14CoNCFe(CN)5]- (where L14=6-methyl-1,4,8,11-tetraazacyclotetradecan-6-amine) were examined. The changes in the redox potentials of the cobalt and iron metal centres with pressure and temperature were a...
