Lignin is a promising alternative to traditional fossil resources for producing biofuels due to its aromaticity and renewability. Pyrolysis is an efficient technology to convert lignin to valuable chemicals, which is beneficial for improving lignin valorization. In this review, pyrolytic behaviors of various lignin were included, as well as the pyrolytic mechanism consisting of initial, primary, and charring stages were also introduced. Several parallel reactions, such as demethoxylation, demethylation, decarboxylation, and decarbonylation of lignin side chains to form light gases, major lignin structure decomposition to generate phenolic compounds, and polymerization of active lignin intermediates to yield char, can be observed through the whole pyrolysis process. Several parameters, such as pyrolytic temperature, time, lignin type, and functional groups (hydroxyl, methoxy), were also investigated to figure out their effects on lignin pyrolysis. On the other hand, zeolite-driven ligni
In a paper recently published in the open-access journal ACS Energy Letters, researchers presented a comprehensive X-ray photoelectron spectroscopy (XPS) study of three Li salts, namely lithium hexafluorophosphate (LiPF6), lithium bis-(trifluoromethanesulfonyl)imide (LiTFSI), and lithiumbis(fluorosulfonyl)imide (LiFSI).
In a paper recently published in the journal ACS Energy Letters, researchers utilized copper(I) thiocyanate (CuSCN) in order to create a hole transport layer (HTL) for various inverted perovskite solar cells (PSCs) and organic solar cells (OSCs). It was determined that the inverted PSCs with doped chlorine had superior performance compared to those with pristine CuSCN.
In a paper recently published in the journal ACS Energy Letters, researchers reviewed the elimination of cobalt (Co) from lithium-ion batteries (LIBs) in order to improve sustainability-related issues and explore the features of Co-free cathodes.
