“…As shown in Figure e, the consumption of refined copper in China is expected to reach 22.2 Mt by 2060, which is 2.4 times that of 2020. Although differential methods are employed, the prediction results of the copper consumption are robust, with a difference of only 2.7% compared to the copper consumption predicted by Wang et al in 2030 and less than 1% compared to the consumption predicted by Dong et al. in 2060 .…”

“…Typically, copper has the advantage of being 100% recyclable and the recycling process cannot reduce its quality. 12 Secondary copper will exceed the primary one in 2032, and China's copper resources are expected to rely only on secondary copper and imported refined copper, with 14.9 and 7.3 Mt by 2060.…”

The transformation of the global power structure caused by the carbon neutrality goal will promote copper consumption. It is crucial to explore the decarbonization pathways of the copper industry to help fulfill greenhouse gas (GHG) emission reduction targets. This study utilized material flow analysis and life cycle assessment methods to investigate 12 different subscenarios based on international trade, circular economy, technology evolution, and environmental market factors. Policy combination scenario is employed to reveal the mechanism of decarbonization. The results show that refined copper consumption in China is expected to increase by 62.3% in 2060 compared to 2020. The GHG emissions of China's copper industry will reach 9.1 million tonnes (Mt) CO 2 e in 2060, technology evolution and environmental market are crucial for realizing carbon neutrality goal of this industry, accounting for 26.4 and 47.2% of emissions reductions, respectively, between 2020 and 2060. International trade and circular economy play important roles in the high-quality carbon peaking stage; however, imported copper and domestic secondary copper will constitute the basic supply of copper resources in China in the long run, and the comparative advantages of them will gradually weaken. Policy combination scenario can achieve the incentive synergy effect, with GHG reduced to 0.5 Mt CO 2 e in 2060. The enhanced application of policies such as material substitution and carbon emission trading will further promote industry to achieve net-zero GHG emission. We suggest regulating the industry's structure based on the international systemic circulation pattern and accelerating the construction of a green circular chain in the short term to achieve sustainable copper supply and high-quality carbon peaking. Promoting a high-quality technology development strategy and enhancing the environmental markets are recommended in the long term to achieve carbon neutrality.

The excess nitrate (NO3‐) in the water mainly comes from agricultural fertilization and industrial wastewater, which breaks the nitrogen balance and poses a serious threat to the environment and human health. Driven by renewable energy, the electrocatalytic reduction of NO3‐ to ammonia (NH3) (ENO3RA) is an environmentally friendly and sustainable technology. Due to its special structure, copper (Cu) is currently one of the best catalysts for ENO3RA, but the reaction mechanism and the structure‐activity relationships of catalysts are still not clear enough. In‐situ characterization is a powerful tool to gain insight into the reaction process. This review introduces several types of in‐situ techniques such as in‐situ XAS, in‐situ FTIR and in‐situ DEMS, summarizes five pathways for converting *NO as the key intermediate to NH3 during ENO3RA on Cu‐based catalysts. The research progress of Cu‐based electrocatalysts in recent years is sorted out from the aspects of composition and structure, and the catalytic mechanisms were discussed with the help of in‐situ characterization technologies. This review would be of help to provide reference characterization methods for exploring the mechanism and the design of electrocatalysts for ENO3RA.
