Botanically Reductive Synthesis Of Au Nanoparticles And Application Of Its Immobilized Carbon-based Catalyst On Botanical Pyrolysis

Recently,countries have been aware of the importance of biomass and highly concerned about the scientific research in this field.In this context,this work applies plant and biomimetic reduction method to synthesize carbon-based Au nanoparticles and step further direct/catalytic pyrolysis was carried out for comparative study.In detail,the following three aspects were experimentally explored and the conclusions were obtained.1?The sizes and the morphs of the prepared Au nanoparticles differ from each other synthesized by green tea,the orange peel,the rose petals,the dragon fruit peel and the Najas minor.The Au nanoparticle size falls into the range of 14-240 nm and appearances into spherical,nearly spherical,cubic,and hexagonal.This way,the size and morphology controls of the Au nanoparticles are achieved by changing the type of plant biomass.2?The effect of plant/chloroauric acid ratio on the reductive synthesis of Au nanoparticles is investigated in this paper as well.Experimental results tell that,with the increasing ratio,the average grain size of Au nanoparticles shows a decreasing trend and narrower particle size distribution.Active ingredients are locked with their amount and the content in the reaction solution through mass balance before and after reaction.Bionically,a prepared simulative reducing solution is proved by better reducing effects,with the two active ingredientss,anthocyanin and glucose.Then comparative loading experiments found the gold loading effect of pitaya peel conquers that of activated carbon through its advantageous botanic surface equipped with oxygen-containing functional groups over that of activated carbon3?Comparative experiments of direct and autocatalytic Najas minor cracking reveal the product of the latter by obviously improved yield,HHV,oil quality and reduced nitrogen content as well.The autocatalytic cracking features more yields of long-chain hydrocarbons and alcohols,beneficial to the prospection of power oil.More importantly,Najas minor carbon-base is observed to keep Au nanoparticles ot of agglomeration at as high as 600?.In conclusion,through the size and morphology regulate of Au nanoparticles prepared by plant reducing,the information of types and proportions are obtained of effective functional components.Bionic synthesis improves the efficiency of synthesis with simulated reduction solution.In autocatalytic thermal cracking of Najas minor by carbon-based Au nanoparticles are effectively option to inhibit Au nanoparticle agglomeration at higher temperatures,along with improved cracking conversion and product distributive profile.
