The petrochemical industry is traditionally a high energy consumption industry, thus saving in this of great significance terms trying to achieve the national goal “carbon-peak and carbon neutrality” China. Diesel one main products enterprises. diesel hydrotreating (HDT) unit relatively due reaction temperature pressure HDT reactors. In order further explore units under different operating cond...
Platinum group metal-free (PGM-free) catalyst with different loadings was investigated in air breathing electrodes microbial fuel cells (MFCs). Firstly, the electrocatalytic activity towards oxygen reduction reaction (ORR) of the catalyst was investigated by rotating ring disk electrode (RRDE) setup with different catalyst loadings. The results showed that higher loading led to an increased in ...
We report a new approach, termed "growth by nanopatterned host-medicated catalyst" (NHC growth), to solve nonuniformities of Si nanowires (NWs) grown on amorphous substrates. Rather than pure metal catalyst, the NHC uses a mixture of metal catalyst with the material to be grown (i.e., Si), nanopatterns them into desired locations and anneals them. The Si host ensures one catalyst-dot per-growth...
Microbial lipids hold great promise as biofuel precursors, and research efforts to convert such renewable diesel fuels have been increasing in recent years. In contrast the numerous literature reviews on growing, characterising extracting from oleaginous microbes, converting vegetable oils hydrocarbon fuels, this review aims provide insight into aspects that are specific hydroprocessing microbi...
Y-junction carbon nanocoils (Y-CNCs) were synthesized by thermal chemical vapor deposition using Ni catalyst prepared by spray-coating method. According to the emerging morphologies of Y-CNCs, several growth models were advanced to elucidate their formation mechanisms. Regarding the Y-CNCs without metal catalyst in the Y-junctions, fusing of contiguous CNCs and a tip-growth mechanism are consid...
