In response to climate change and continued reliance on traditional high-carbon fossil fuels, promoting the transition toward sustainable energy systems by development of low-carbon energy resources has been seen as the main strategy for mitigating and solving global climate change. However, the promotion of low-carbon energy also faces material supply risks. To provide a reference for the steady and rapid development of renewable energy and other energy in the future energy market, this paper considers renewable energy prediction based on a long-and short-term memory network model as well as the growth rate changes of crude oil, natural gas, nuclear energy, financial revenues, and expenditure. In the prediction process, it is found that natural gas will be a strong competitor for the development of renewable energy in the future. When natural gas grows too quickly, the growth of renewable energy will be negative. On the other hand, when the monthly growth rate of natural gas and crude oil is smaller than that of nuclear energy, renewable energy will display a growth trend, and the rate will increase with the growth of natural gas and nuclear energy. What is more, wind and solar energy will be limited by metallic materials, such as Dy, Nd, Te, and In. Improving the energy density of metals plays a key role in China's transition to a low-carbon energy structure.

Fe-doped NaBiO nanoscaled compounds were prepared by hydrothermal method and evaluated as a highly efficient photo-Fenton-like catalyst under visible light irradiation. The Fe-doped NaBiO compound had a specific surface area of 41.42 m g, which is considerably larger than that of NaBiO nanoparticles (28.81 m g). The compound exhibited an excellent visible light-Fenton-like catalysis activity, which is influenced by the iron content of the compound and the pH value of the solution. Under the optimal conditions, the Fe-doped NaBiO compound led to fast degradation of Nonylphenol with an apparent rate constant of 5.71 × 10 min, which was 8.23-fold of that achieved by using NaBiO. The significantly enhanced visible light-Fenton-like catalytic property of the Fe-doped NaBiO was attributed to the large surface area and the high adsorption capacity of the compound, and the Fenton catalytic ability of iron in the compound.

Based on the present situation of general industrial waste management in Beijing as the research object, analyzed the 2008-2017, the trend of general industrial waste emissions in Beijing, several main waste disposal, the change of the quantity and the comprehensive utilization of the status quo, analysis of a series of problems, put forward three countermeasures of general industrial solid waste management.
