Abstract
Millimeter-sized porous carbon spheres (MPCS) with both controllable interior architecture and high mechanical strength are highly desired for practical applications, but there is no efficient method to synthesize these materials. Here, we report a strategy to fabricate millimeter-sized porous carbon spheres by harnessing the liquid marble phenomenon. This strategy enables us to obtain a series of MPCS with tunable interior architectures, such as honeycombed MPCS, foam-like MPCS, cavity-containing MPCS and hollow MPCS, which add new members to carbon microsphere family. Crucially, the mechanical strength of MPCS reaches as high as 14.6 N, favoring its practical applications. Moreover, our protocol allows for nitrogen element and metal to be in situ incorporated within the body of MPCS, leading to an efficient catalyst for levulinic acid (LA) hydrogenation or benzene hydrogenation. Impressively, turnover numbers (TONs) of 113000 in the LA hydrogenation and 480 h of continuous benzene hydrogenation with TONs of 116000 are achieved, which highlights the potential in engineering applications of these novel microspheres.
