Biomass-based production of functional carbon materials for energy conversion and storage (2023)

Introduction

With the rapid development of the world economy, non-renewable energy sources are consumed in large quantities and bring a series of environmental problems. The importance of sophisticated, high-quality use of non-renewable energy sources such as coal is becoming increasingly important [1]. Meanwhile, green and renewable energy sources such as solar, wind, hydroelectric, tidal and geothermal have attracted much attention. However, these renewable energy sources suffer from variability, regionality and high cost, which limit their widespread application. Therefore, it is very important to develop efficient and environmentally friendly technologies for energy conversion and storage [2], [3], [4], [5]. Various energy conversion and storage technologies have been developed, such as solar cells [6], [7], [8], [9], fuel cells [10], [11], [12] and supercapacitors [13]. , [14], [15], [16], [17], Lithium ion batteries [18], [19], [20], [21], [22], [23], [24], Sodium ion batteries [25], [26], [27], [28], [29], [30], potassium ion batteries [31], [32], [33], [34] and Li-S batteries [35 ], [36], [37], [38] and Na-S batteries [38], [39] etc.

Carbon materials have been extensively studied due to their high specific surface area (SSA), tunable pore structure, and excellent chemical stability. Typically, carbon materials are made from fossil fuels using energy-intensive, environmentally unfriendly and expensive synthetic processes. In recent years, countries around the world are paying more and more attention to saving energy and reducing emissions. In order to achieve the goal of "carbon neutrality", great efforts have been made in the development strategy of green environmental protection worldwide. As a green raw material, biomass has the advantages of abundant, renewable, ecologically sound and cheap sources. Carbon materials derived from renewable biomass have attracted the attention of researchers in recent years. Biomass is any organic organism (living or dead) that inherently produces chemical energy, e.g. terrestrial and aquatic organisms, municipal solid waste, animal waste, forestry and agricultural waste [40], [41], [42]. When this waste is dumped or incinerated, it not only pollutes the environment but also causes climate change by increasing CO emissions.2into the atmosphere, which goes against the sustainable development strategy of our modern society. The maximum possible conversion of the carbon stored in these biomass resources into functional carbon materials opens a new opportunity to convert biomass residues into high value-added products. Compared to fossil fuel-based carbon materials, biomass-based carbon materials have the following notable advantages: renewable capacity; biogenetic materials with unique structural advantages that can be produced by a simple biomodeling method. intrinsically porous or hierarchically porous structure that can provide a highly accessible surface and a wide pathway for electrolyte ions; Most biomasses contain N, S and P elements, so self-doping can occur in the synthesis process through the formation of active additives sites in biomass-based carbon materials. These properties make biomass-based carbon materials one of the most promising functional materials in the fields of energy conversion and storage.

Therefore, there is an urgent need for an updated review on the rational design and fabrication of biomass-based functional carbon materials (BFCs) with multidimensional structures and their applications in energy conversion and storage, as shown in Fig. 1. First, in this review, methods for BFC synthesis are described, including carbonization, activation, and functionalization. Second, the multidimensional structures and unique properties of BFCs are presented and highlighted. Third, the advances in the application of BFCs in the fields of energy conversion and storage in recent years are summarized. This review then provides a detailed analysis of how to determine the relationships between the structure and performance of BFCs. This helps researchers to logically classify the rational design and controlled synthesis of high-performance BFCs in different research fields. Application. Finally, the main challenges and opportunities that remain for BFCs going forward are discussed and outlined.

Biomass-based production of functional carbon materials

As a renewable resource, biomass has received significant attention in energy conversion and storage due to its abundant sources, diverse structures, low cost, and renewable energy.

The perfect combination of these methods can convert biomass into valuable carbon materials [43]. Porous carbons with

BFC Structures

After billions of years of natural evolution, the organizational structure of natural organisms has been perfectly preserved and inherited. Starting from its original form, carbon obtained from biomass can be perfectly modified by physical or chemical methods.
