Cobalt tetra-2,3-pyridiniumporphyrazinato with sulfonic acid tag [Co(TPPASOH)]Cl was produced and catalyzed the synthesis of -aminocarbonitriles, cyclohexa-1,3-dienamines and 2-amino-3-cyanopyridines. The synthesis of 2-amino-3-cyanopyridines by using [Co(TPPASOH)]Cl proceeded a cooperative vinylogous anomeric based oxidation mechanism. [Co(TPPASOH)]Cl can be recycled and reused six times with a marginal decreasing of its catalytic activity.

The rapid growth of electric vehicles (EVs) in China challenges raw material demand. This study evaluates the impact of recycling and reusing EV batteries on reducing material demand and carbon emissions. Integrating a national-level vehicle stock turnover model with life-cycle carbon emission assessment, we found that replacing nickel-cobalt-manganese batteries with lithium iron phosphate batteries with battery recycling can reduce lithium, cobalt, and nickel demand between 2021 and 2060 by up to 7.

Herein we report a cobalt-catalyzed hydroglycosylation of terminal alkynes, employing bench-stable ortho-iodobiphenyl (oIB) substituted sulfides as glycosyl donors. This reaction occurs with high stereo- and regioselectivity to afford E-configured vinyl α-C-glycosides, a class of compounds nontrivial to access by previous methods. The use of a bis(oxazoline) ligand with bulky side chains is critical for the high selectivities observed.

Altering the electron distribution within a catalyst to manipulate internal charge migration pathways is an effective strategy for achieving high efficiency in carrier separation and migration, which is essential for the advancement of photocatalytic water oxidation technologies. We have employed atomic layer deposition (ALD) to construct a BiFeO/CuO (BFO/CuO) heterojunction with a specific CuO thickness, resulting in a Z-type junction (BFO/CuO50) characterized by a robust internal electric field. This junction facilitates the spatial separation of charge carriers, thereby enhancing their migration efficiency.

Nickel-rich cobalt-free layered oxide cathode with Ni contents no fewer than 90 % has received extensive attention in the field of lithium-ion batteries due to its excellent specific capacity and low cost, but serious capacity degeneration induced by structural deterioration and interfacial instability greatly hamper their further development. Herein, the Sb-modified LiNiMnO materials from the interface to interior have been designed and fabricated to overcome the above issues. On the one hand, the introduction of Sb-ion in interior of grains can generate Sb-O chemical bond with high dissociation energy, which contributes to reinforce the chemical and structural stability.
