摘要

Abstract

Cellulose and its derivatives are natural materials with high carbon contents

but it is challenging to convert their carbon into high value-added carbonaceous materials (

e.g.

graphene). Here

an approach to convert the carbon in cellulose into N

P co-doped porous graphene (LIG) materials

via

laser induction is proposed. Cellulose nanofibrils (CNFs)

a cellulose derivative with high dispersion uniformity and abundant surface hydroxyl groups

were easily formed on a bulk substrate (thickness ≥ 5 mm) containing ammonium polyphosphate (APP). Then

a 10.6 μm CO

laser was used to scribe for 1-5 passes on the CNFs/APP substrate under an ambient environment to produce N

P co-doped porous LIG. Upon increasing the number of laser scribing passes

the

of LIG first increased and then decreased

reaching a maximum of 1.68 at 4 passes. The good pore structure and low resistance also showed that 4 laser passes were ideal. Besides

the N

P co-doped LIG also showed excellent electrochemical performance

with a specific capacitance of 221.4 F?g

-1

and capacitance retention of 89.9%. This method exploits the advantages of na

nocellulose and overcomes the difficulties associated with directly compounding cellulosic materials

providing a method for the further development of biomass nanomaterials.
