“…Figure 9 shows that the solution of this model was a saddle point, where the predicted yield of LA was 42.01%. Wang et al (2013) observed the same phenomenon, in which longer reaction time and higher Pb(II) concentration can no longer enhance the formation of LA. They performed the conversion of microcrystalline cellulose into LA in the presence of Pb(II) and found that further increases in the concentration of Pb(II) will only slightly increase the yield of LA, which plateaued at ~70%.…”

“…5a). This can be attributed to the fact that in the presence of Pb(II), the reaction process will shift from dehydration of sugars (glucose and xylose), yielding 5-HMF or furfural, into retro-aldol fragmentation of sugars (glucose and xylose), yielding LA (Wang et al 2013).…”

“…The separation and recovery of Pb(II) from the catalytic system should be considered before practical application. It was reported by Wang et al (2013) that Pb(II) in the reaction solution could be simply recovered using a cation exchange resin (Amberlite IR-120 resin). Thus, using this available technique, the risk of using Pb(II) as a catalyst can be reduced.…”

“…The glucose-based route incorporates glycolysis of glucose, which involves isomerization to fructose (Eriksen et al 1998). The introduction of Pb(II) results in the selective cleavage of the C-C bond in C3-C4 of fructose and C2-C3 bond in xylose into trioses (dihydroxyacetone and glyceraldehyde), followed by the selective conversion of trioses (retro-aldol condensation) and dehydration of pyruvaldehyde into LA (Yu et al 2008;Wang et al 2013). …”

“…Studies have reported the use of transition metal ions such as Zn(II), Ni(II), Cr(III), Al(III), and Pb(II) for biomass conversion to LA and levulinic acid (Peng et al 2010;Wang et al 2013;Sitompul et al 2014). Wang et al (2013) reported that Pb(II) ions are one of the most effective metal ions for the conversion of lignocellulosic materials into LA. Therefore, Pb(II) ions were chosen as the catalyst in this study.…”

Lactic acid (LA) is a potential platform chemical that can be produced from lignocellulosic biomass. The development of a cost-competitive, catalyticbased LA production system is gaining significant attention in modern biorefineries. A series of experimental study was carried out to investigate the chemocatalytic effect of the conversion of oil palm empty fruit bunch (EFB) fibers into lactic acid under hydrothermal conditions. Synthesis of chemicals from lignocellulosic biomass involves complex mechanisms because of the complex composition of the biomass. Therefore, experimental parameters, i.e., temperature, Pb(II) concentration, and reaction time were studied. It was found that production of LA is highly dependent on the experimental conditions. In this study, the highest LA yield obtained from EFB fibers was > 46% (230 °C, 2 mM Pb(II) after 4 h of reaction). However, a similar yield can be achieved either using higher Pb(II) and shorter reactions time or vice versa. The selective production of chemical compounds (glucose, 5-hydroxymethyl furfural (5-HMF), furfural, levulinic acid, and lactic acid) from EFB fibers is highly dependent on the availability of Pb(II) ions.

The introduction of surface functional groups onto graphene can provide additional pseudocapacitance for supercapacitors. However, the compensation for the loss of electrical conductivity arising from the disruption of the conjugated system remains a big challenge. Here, a novel strategy is reported for the design of oxygen clusters distributed in graphene with "paddy land" structure via a low-temperature annealing process. Moreover, the distribution, content, and variety of oxygen groups and the conductivity of reduced graphene oxide (RGO) can be easily adjusted by annealing temperature and time. First-principles calculations demonstrate that "paddy land" structure exhibits conjugated carbon network, ultralow HOMO-LUMO gap, and long span of atomic charge values, which are beneficial for the enhanced pseudocapacitance and rate performance. As a result, the functionalized graphene (GO-160-8D) exhibits high specific capacitance of 436 F g −1 at 0.5 A g −1 , exceeding the values of previously reported RGO materials, as well as excellent rate performance (261 F g −1 at 50 A g −1 ) and cycling stability (94% of capacitance retention after 10 000 cycles). The findings may open a door for finely controlling the location and density of functionalities on graphene for applications in energy storage and conversion fields via a green and energy-efficient process.
