“…In order to solve the above problems, Yang et al [28] used the method of carbonizing corrugated paper to prepare an integrated binder-free air cathode with low cost and good scalability, and by doping FePc, the ORR catalytic performance of the integrated cathode was further improved, achieving 830 mW/m −2 maximum power density. Furthermore, Yang et al [29] fabricated an integrated binder-free tubular air cathode with high mechanical strength by directly carbonizing bamboo tubes. e preparation method has the advantages of a simple and convenient preparation process.…”

In recent years, global warming caused by the greenhouse effect has become one of the greatest threats to mankind. This will have a serious impact on the environment and human body, such as land desertification, increase in ocean acidity, sea level rise, and increase in pests and diseases; affect people’s normal work and rest; and make people feel dizzy and nauseated. Excessive emissions of carbon dioxide (CO2), the main component of the greenhouse gas, have contributed to the continued rise in Earth’s temperature. Although the world is vigorously developing clean energy to reduce carbon emissions, it will not replace fossil fuels in the short term. The conversion of biomass into energy is the most important way of energy utilization. Biomass energy refers to the solar energy stored in biomass in the form of chemical energy and is the fourth major energy source after oil, coal, and natural gas. At present, biofuels have gone through three developmental stages, which can be divided into first-generation biofuels, second-generation biofuels, and third-generation biofuels according to the types of raw materials and development history. The first generation of biofuels produced from food crops, such as bioethanol derived from sucrose and starch, has already entered the energy market. However, because the first generation of biofuels uses food crops as raw materials, there is a phenomenon of “competing with people for food,” and it is difficult to achieve large-scale application. To avoid the problem of food shortages, second-generation biofuels produced from nonfood crops, such as wood fiber, have been developed. Microalgae biomass energy is favored by governments and scholars all over the world because of its unique advantages of fast reproduction speed and high oil content. The cultivation of microalgae does not occupy traditional farmland, and the marginal land such as mountains, oceans, and deserts can cultivate microalgae, or develop microalgae cultivation in the air through the innovation of microalgae photosynthetic reactors. When municipal wastewater, food industry wastewater, and aquaculture wastewater are used as the medium for large-scale cultivation of microalgae, and waste gas from biogas power generation, flue gas from coal power plants, and industrial waste gas from fermentation are used as the CO2 gas source for large-scale cultivation of microalgae, it can be further reduced. The comprehensive production cost of microalgae bioenergy plays a significant emission reduction effect. Combining the above advantages, the use of microalgae to produce first- or second-generation bioenergy has become a new research direction. This study focuses on the review of microalgal biomass in fuel, nonfuel, wastewater treatment, and fuel cell.

“…However, this method is difficult to transplant to the cathode made by biomass-derived carbon. Yang et al , prepared two kinds of monolithic binder-free cathodes using corrugated paper and bamboo tubes as the precursors. With the monolithic carbon structure derived from the precursors and heteroatom doping during pyrolysis, the obtained biocarbons served as ORR catalysts and support substrates simultaneously (Figure ).…”

Natural biomass is a promising candidate for the preparation of heteroatom-doped carbons that can be used as effective electrode catalysts for microbial fuel cells (MFCs), due to its intriguing features, such as high abundance, rich heteroatom contents, and low cost. In this review, we summarize recent process in the design and fabrication of MFC electrodes based on biocarbons; discuss the effects of preparation methods, bacteria/electrode interaction, pore structure, and assembly procedure on the electrode and cell performance; and conclude with a perspective highlighting the strategies and critical challenges in electrode fabrication for further enhancement of the device performance.

“…In most cases, oxygen in the air is used as a sustainable oxidizer at the cathode [6]. The oxygen enters the catalytic layer and reacts with the electrons and protons flowing into the cathode to form water under the action of the cathode catalyst [7,8]. However, currently, the development of more effective and stable catalysts is highly desired for the cathodic oxygen reduction reaction (ORR) in MFCs [9][10][11][12][13].…”

Metal, as a high-performance electrode catalyst, is a research hotspot in the construction of a high-performance microbial fuel cell (MFC). However, metal catalyst nanoparticles and their dispersed carriers are prone to aggregation, producing catalytic electrodes with inferior qualities. In this study, Pd is uniformly dispersed on the graphene framework supported by carbon black to form nanocomposite catalysts (Pd/GO-C catalysts). The effect of the palladium loading amount in the catalyst on the catalytic performance of the air cathode was further studied. The optimized metal loading afforded a reduced resistance and improved accessibility of Pd particles for the ORR. The maximum current output of the 0.250 Pd (mg/cm2) MFC was 1645 mA/m2, which is 4.2-fold higher than that of the carbon paper cathode. Overall, our findings provide a novel protocol for the preparation of high-efficient ORR catalyst for MFCs.
