Here, we propose a facile approach for tribochemically atom transfer (tribo-ATRP) that relies on contact-electro-catalysis (CEC) between titanium oxide (TiO2 ) particles CuBr2 /tris(2-pyridylmethylamine (TPMA), without any input. Under friction induced by stirring, TiO2 are electrified, continuously reducing /TPMA into CuBr/TPMA, thereby conversing alkyl halides active radicals start ATRP.
