Abstract Ordered mesoporous carbons (OMCs) have demonstrated great potential in catalysis, and as supercapacitors adsorbents. Since the introduction of organic–organic self-assembly approach 2004/2005 until now, direct synthesis OMCs is still limited to wet processing phenol-formaldehyde polycondensation, which involves soluble toxic precursors, acid or alkali catalysts, requires multiple steps, thus restricting widespread application OMCs. Herein, we report a simple, general, scalable sustainable solid-state nickel with uniform tunable mesopores (∼4–10 nm), large pore volumes (up 0.96 cm 3 g −1 ) high-surface areas exceeding 1,000 m 2 , based on mechanochemical assembly between polyphenol-metal complexes triblock co-polymers. Nickel nanoparticles (∼5.40 nm) confined cylindrical nanochannels show thermal stability at 600 °C. Moreover, offer exceptional activity hydrogenation bulky molecules (∼2 nm).
