Two kinds of platinum catalysts with different morphologies were prepared by loading platinum atoms on titanium dioxide nanosheets via electrostatic adsorption. Scanning electron microscope (SEM), X-ray powder diffraction (XRD) and transmission electron microscope (TEM) characterization show that the morphology and structure of platinum could be controlled by changing the platinum loading. With low Pt loading (0.2wt%), the platinum atoms were mainly nanoclusters with a radius of about 2 nm. When the Pt loading increased to 1wt%, the platinum atoms stack into nanoparticles on the titanium dioxide nanosheets. The catalytic hydrogen evolution activity of titanium dioxide nanosheets can be improved obviously by regulating the platinum loading and nanostructure. Under AM1.5 solar light, the Tafel slope of both catalysts were less than 100 mV/dec, i.e. 56 and 90 mV/dec, respectively. Compared with TiO 2-Pt1% catalyst, TiO 2-Pt0.2% has a more ideal metal-semiconductor interface, which is favorable for photogenic electrons to migrate to the surface of platinum nanoclusters, and thus perform a higher catalytic activity. This experiment provides a new way for preparing platinum catalysts with high efficiency.

“…The integrated systems were capable of producing H 2 effectively from lignocellulosic materials that are traditionally considered as recalcitrant agricultural wastes, including corn stover, sugar beet, plant leaves, and corn stalk, etc. [83][84][85][86]. When combined with fermentation, the average overall increases of H 2 production rate and yield were 148% (ranging from 42 to 538%) and 225% (ranging from 2 to 400%), respectively [18].…”

Background: Bioelectrochemical systems (BESs) are emerging energy-effective and environment-friendly technologies. Different applications of BESs are able to effectively minimize wastes and treat wastewater while simultaneously recovering electricity, biohydrogen and other value-added chemicals via specific redox reactions. Although there are many studies that have greatly advanced the performance of BESs over the last decade, research and reviews on agriculture-relevant applications of BESs are very limited. Considering the increasing demand for food, energy and water due to human population expansion, novel technologies are urgently needed to promote productivity and sustainability in agriculture. Methodology: This review study is based on an extensive literature search regarding agriculture-related BES studies mainly in the last decades (i.e., 2009–2018). The databases used in this review study include Scopus, Google Scholar and Web of Science. The current and future applications of bioelectrochemical technologies in agriculture have been discussed. Findings/Conclusions: BESs have the potential to recover considerable amounts of electric power and energy chemicals from agricultural wastes and wastewater. The recovered energy can be used to reduce the energy input into agricultural systems. Other resources and value-added chemicals such as biofuels, plant nutrients and irrigation water can also be produced in BESs. In addition, BESs may replace unsustainable batteries to power remote sensors or be designed as biosensors for agricultural monitoring. The possible applications to produce food without sunlight and remediate contaminated soils using BESs have also been discussed. At the same time, agricultural wastes can also be processed into construction materials or biochar electrodes/electrocatalysts for reducing the high costs of current BESs. Future studies should evaluate the long-term performance and stability of on-farm BES applications.
