“…According to the simulation of building energy consumption, energy consumption for buildings can be reduced by 9.8% when using thermal insulation materials in severe cold regions in winter. The reasons for high energy consumption in Chinese buildings are mainly due to the backward structure of the building envelope [102,103]. A total of 20% to 50% of the utilization of building energy is consumed by the exterior heat transfer structure.…”

“…A total of 20% to 50% of the utilization of building energy is consumed by the exterior heat transfer structure. Improving building exterior insulation materials is the least expensive, has the simplest operation, and is the fastest way to improve heating efficiency [8,102,104]. The common organic energy-saving materials in China are phenolic resin foam materials and polystyrene foam insulation boards.…”

Coal-fired heating is the main method of heating in China, causing serious air pollution and large amounts of CO2 emissions. Decarbonizing heating is important to reduce carbon emissions, and choosing a suitable heating technical scheme is conducive to the early realization of carbon neutrality in China. Coal to gas and coal to electricity transformation projects were carried out in 2017 and achieved remarkable effects. This study compares the current domestic and international clean heating modes, where gas heating, electric heating, heat hump heating, biomass heating, and solar heating coupling system are taken into account. The heating technology potential and heating support aspects, including the industrial sector, building sector, carbon capture and storage (CCS) technology, and publicity are explored as well. Regarding the actual situation in China, a comparative analysis is also conducted on the different types of heat pumps, and then an optimal heating scheme for urban and rural areas is proposed. It is suggested that the urban area with centralized heating can install ground source heat pumps, and the rural area with distributed heating can apply a coupling system of solar photovoltaics to ground source heat pumps (PV-GSHP). Based on current policies and standards support, this study calculates the carbon emissions of this scheme in 2030 and provides a detailed analysis of relevant parameters. The feasibility and superiority of the scheme are confirmed by comparison and discussion with other studies. Moreover, specific measures in planning, subsidy, construction, and electricity are proposed to implement the heating scheme. This study provides a reference for the mode selection and technical scheme of heating decarbonation in China, and that could be also considered in other regions or countries.

“…The rational design of highly efficient materials requires an atom-level understanding of their structure-performance relationship. [1][2][3][4][5] However, under working conditions, most materials undergo a structural reconstruction accompanied by an unpredictable performance. [6][7][8][9] For example, some bimetallic catalysts like Au-Ag alloys can exhibit dynamic geometrical and compositional reconstruction during the reaction, which generates active sites to boost performance.…”
