英文摘要	Mass production of high-quality graphene with low cost is the footstone for its widespread practical applications. We present herein a self-limited growth approach for producing graphene powders by a small-methane-flow chemical vapour deposition process on naturally abundant and industrially widely used diatomite (biosilica) substrates. Distinct from the chemically exfoliated graphene, thus-produced biomorphic graphene is highly crystallized with atomic layer-thickness controllability, structural designability and less noncarbon impurities. In particular, the individual graphene microarchitectures preserve a three-dimensional naturally curved surface morphology of original diatom frustules, effectively overcoming the interlayer stacking and hence giving excellent dispersion performance in fabricating solution-processible electrodes. The graphene films derived from as-made graphene powders, compatible with either rod-coating, or inkjet and roll-to-roll printing techniques, exhibit much higher electrical conductivity (similar to 110,700 Sm-1 at 80% transmittance) than previously reported solution-based counterparts. This work thus puts forward a practical route for low-cost mass production of various powdery two-dimensional materials.; National Basic Research Program of China [2013CB932603, 2016YFA0200103, 2012CB933404, 2012CB921404, 2013CB934600]; National Natural Science Foundation of China [51520105003, 51432002]; Specialized Research Fund for the Doctoral Program of Higher Education of China [20120001130010]; Beijing Municipal Science and Technology Planning Project [Z151100003315013]; SCI(E); PubMed; ARTICLE; yanfengzhang@pku.edu.cn; zfliu@pku.edu.cn; 13440; 7
