From e-waste to gold: A pathway to CO₂ sustainability

A Cornell-led research team has developed a method for extracting gold from electronics waste, then using the recovered precious metal as a catalyst for converting carbon dioxide (CO2), a greenhouse gas, to organic materials. The method could provide a sustainable use for some of the approximately 50 million tons of e-waste discarded each year, only 20% of which is recycled, according to Amin Zadehnazari, a postdoctoral researcher in the lab of Alireza Abbaspourrad, the Yongkeun Joh Associate Professor of Food Chemistry and Ingredient Technology in the College of Agriculture and Life Sciences. Zadehnazari synthesized a pair of vinyl-linked covalent organic frameworks (VCOFs) to remove gold ions and nanoparticles from circuit boards in discarded electronic devices. One of his VCOFs was shown to selectively capture 99.9% of the gold and very little of other metals, including nickel and copper, from the devices.

you've changed a lot.

another one of my recent ones, drawing these took 10 years out of my life 🙏🙏(also made a mistake on his shirt, but let's ignore that)

Cobalt ions, not covalent organic frameworks themselves, drive catalytic activity, study finds

Covalent organic frameworks (COFs) are less stable as catalysts than previously thought but remain highly active. COFs are promising designer catalysts, for example for the sustainable production of chemicals and fuels. Their properties can be adjusted very specifically to catalyze a desired reaction based on their precise tunability, both in terms of molecular structure and chemical compositions. However, researchers at Ruhr University Bochum, Germany, and the Max Planck Institutes for Solid State Research (MPI-FKF) and for Sustainable Materials (MPI-SusMat) have shown that the catalytic activity is not generated by the COFs themselves. Instead, the cobalt ions detach from the scaffold and transform into oxidic nanoparticles that actually facilitate the catalysis. The team describes these results in the journal Advanced Science. "With the knowledge gained from this study, we will be able to design catalysts from organic frameworks and nanoparticles that are significantly more efficient than COFs designed before," says Professor Kristina Tschulik from Ruhr University Bochum and the RESOLV Cluster of Excellence, who came up with the idea for the study jointly with Professor Bettina Lotsch from the MPI-FKF.

YOU DO IT TO YOURSELF

alternative versions!!!

sorry for the inactivity again 🙏😭

this was actually a failed art piece but its a rlly fun process, so I decided to n experiment something new kinda!!
