“…More interestingly, numerous primary Ge nanoparticles (around 45 nm) are conformably encapsulated and individually isolated by the interlinked carbon shell due to the in‐situ decomposition and carbonization of the TPG molecules under space‐confined vacuum conditions (Figure E). The continuous carbon frameworks are predominantly generated from the gas species in the decomposition step to oligomers, acetylene, radicals, and hydrogen at around 500 °C, very similar to the derivatives from benzene‐based materials after thermal treatment . In addition, Figure H shows these primary GeNPs with obvious (111) and (220) crystal planes.…”

[13] In addition, Figure 1H shows these primary GeNPs with obvious (111) and (220) crystal planes. The corresponding interlayer distances were further determined to be around 0.327 and 0.200 nm, respectively ( Figure 1I).…”

The rational design of a proper electrode structure with high energy and power densities, long cycling lifespan, and low cost still remains a significant challenge for developing advanced energy storage systems. Germanium is a highly promising anode material for high‐performance lithium ion batteries due to its large specific capacity and remarkable rate capability. Nevertheless, poor cycling stability and high price significantly limit its practical application. Herein, a facile and scalable structural engineering strategy is proposed by controlling the nucleation to fabricate a unique hierarchical micro‐nanostructured Ge–C framework, featuring high tap density, reduced Ge content, superb structural stability, and a 3D conductive network. The constructed architecture has demonstrated outstanding reversible capacity of 1541.1 mA h g−1 after 3000 cycles at 1000 mA g−1 (with 99.6% capacity retention), markedly exceeding all the reported Ge–C electrodes regarding long cycling stability. Notably, the assembled full cell exhibits superior performance as well. The work paves the way to constructing novel metal–carbon materials with high performance and low cost for energy‐related applications.

“…The addition of C 2 H 2 then propagates the growth of PAHs molecules. Several studies on C 6 H 6 pyrolysis have demonstrated significant hydrogen production at different temperatures [1,3,[34][35]. Also, C 2 H 2 forms easily in the C 6 H 6 /Ar system [24].…”

“…For H 2 formation shown in Figure 6(a), H-atom production steps (2) and (8) dominate as expected. The removal of H by H ϩ C 6 H 5 CH 2 (5), negatively affects the yields of H 2 . For CH 4 , as revealed by Figure 6(b), reactions (8) and (11) have strong positive effects, whereas reactions (5) and (10) negatively affect the yield of CH 4 as can be expected.…”

Kinetic data of Brooks et al. [3] on the decomposition of C 6 H 6 near 1000 K have been analyzed by computer modeling. The observed overall 3/2-order kinetics could be accounted for by a mechanism composed of 4 key reactions involving H atoms and C 6 H 5 radicals using recently acquired rate constants. However, the appearance of CH 4 and the enhanced H 2 yields could only be explained by invoking the reactions of ϳ0
