Copper scrap insurance Metal-organic frameworks (MOFs) have been attracting a lot of attention as promising materials for CO2 conversion due to their unique properties such as high surface area, porosity, and tunable chemistry. However, the selective reduction of CO2 to value-added products such as ethanol remains a challenging task. In a recent study, a cooperative copper centre in a MOF was proposed as an efficient catalyst for the conversion of CO2 to ethanol. The MOF used in the study was synthesized by incorporating a copper centre in the framework structure. The copper centre was designed to have a cooperative effect with neighbouring copper centres, which was expected to enhance the selectivity towards ethanol production. The catalytic performance of the MOF was evaluated in a batch reactor under mild reaction conditions (25 В°C and 1 atm CO2 pressure). The results showed that the cooperative copper centre in the MOF exhibited high selectivity towards ethanol production (90%), with a conversion rate of 32 Ојmol g^-1 h^-1. The formation of ethanol was attributed to the reduction of CO2 by the copper centre, which was facilitated by the neighbouring copper centres. The cooperative effect was found to be critical to achieving high selectivity towards ethanol and suppressing the formation of undesirable by-products such as methanol and formic acid. Furthermore, the catalyst showed good stability over multiple cycles, indicating its potential for practical applications. The proposed strategy of designing cooperative metal centres in MOFs could pave the way for the development of efficient and selective catalysts for CO2 conversion. In conclusion, the cooperative copper centre in a MOF demonstrated high selectivity towards ethanol production from CO2. The results suggest that designing cooperative metal centres in MOFs could be a promising approach for developing efficient and selective catalysts for CO2 conversion Metal scrap recovery yard Copper scrap grades Copper scrap innovation Copper scrap compounding Sustainable copper processing Metal scrap dealer
Copper scrap logistics Copper has been mined for thousands of years, with evidence of its use in tools and decorative objects dating back to 9000 BC. The first large-scale copper mining operation was established in the Middle East around 4500 BC, and the metal quickly became an important commodity in many ancient civilizations. In Europe, copper mining has been a significant industry since the Bronze Age, and the abundant deposits in the Balkans, Cyprus, and the British Isles fueled the development of trade networks and the growth of urban centers. In the Americas, indigenous peoples of South America were working with copper as early as 500 AD, and the arrival of Spanish conquistadors in the 16th century led to the exploitation of rich copper deposits in present-day Chile and Peru. The Industrial Revolution brought about a major increase in demand for copper, as it was used extensively in electrical wiring and machinery. This spurred the development of new technologies for mining and refining copper, including the use of steam engines and electrolysis. With new industrial machinery and techniques, mining operations became larger in scale and more efficient. Today, copper is one of the most important metals in the world, used in a vast array of applications ranging from construction and infrastructure to electronics and renewable energy. Significant copper mining operations can be found all over the globe, with major producers including Chile, the United States, and Peru. As demand for this versatile metal continues to grow, it is certain to remain a vital part of our economy and way of life for years to come Metal waste resale Copper scrap collection center Copper scrap industry standards Copper scrap stock management Copper scrap purity testing Scrap metal drop-off
