observed the presence of trace Cu impurities in the form of isolated single atoms on the as-prepared thin-film graphene surface when CVD process underwent on a Cu film catalyst substrate.34 In terms of the whole conversion process and resultant product, these CVD-assisted strategies can be ...
Although this method enables the realization of mass production of graphene powders with a relatively low cost, the materials obtained show quite poor crystal quality with high defect density, thereby greatly limiting the fast electron transport in high-energy-density and high-power-density energy ...
at the edge of the large film. Each type of the 2D films prepared by this process has a different thickness: 4.1 nm for Ga2O3, 3.2 nm for In2O3, and 4.4 nm for SnO. It has been proven by experiments that the printing technology can reproduce the formation of uniform centime...
Large-scale implementation of electrochemical hydrogen production requires several fundamental issues to be solved, including understanding the mechanism and developing inexpensive electrocatalysts that work well at high current densities. Here we addres
Graphene-skinned alumina fiber fabricated through metalloid-catalytic graphene CVD growth on nonmetallic substrate and its mass production Graphene growth on widely used dielectrics/insulators via chemical vapor deposition (CVD) is a strategy toward transfer-free applications of CVD graphene for the realizat...
28, 29, 30 A chemical vapor deposition (CVD) method for growing large-scale graphene film was successfully developed, allowing further use of graphene in practical applications and mass roll-to-roll manufacturing.29 In addition, graphene provides a good interfacial substrate and possesses low ...
can be indicated by the change in film color and the SEM images. Kaner et al. [26] also used a LightScribe DVD burner to fabricate graphene micro-supercapacitors over large areas by direct laser writing on graphite oxide films. Thanks to the precision of a laser, the desired graphene ...
around Ir atoms is richer and the Ir–O coordination number is 5.8 close to an ideal coordination of 6 [77]. The XAS is conducted to investigate Co oxidation states, electron occupancies, and coordination environments of PrBaCo2O6films with the {100} facets. The XAS results indicated that...
Here, recent progress toward the mass production of CVD graphene films is summarized, including the manufacturing process, equipment, and critical process parameters. Moreover, the large‐scale homogeneity of graphene films and fast characterization methods are also discussed, which are crucial for ...
