Precise activation of C-C bonds for recycling and upcycling of plastics.

observed that an increased density of BAS on the Al-SBA-15 achieved a higher activation efficiency and a decreasing trend of the degradation temperature, owing to a greater number of sites capable of directly activating the C aliph –C aliph bonds ( Fig. 3b and c ). 59 Furthermore, similar trends were obtained in the activation cracking of C aliph –C aliph bonds, employing LAS-rich β-zeolites and ZSM-12, respectively. 60 Briefly, increasing both LAS and BAS concentrations can boost the activation of C aliph –C aliph bonds, respectively.
