| Graphene-supported Pd–Pt alloy nanoflowers: In situ growth and their enhanced electrocatalysis towards methanol oxidation Original Research Article International Journal of Hydrogen Energy, Available online 15 April 2015, Pages Ke Wu, Qian Zhang, Dongmei Sun, Xiaoshu Zhu, Yu Chen, Tianhong Lu, Yawen Tang
Graphical abstractEvenly-spread porous Pd–Pt alloy nanoflowers on reduced graphene oxide nanosheets, in situ grown by one-pot polyallylamine hydrochloride-assisted co–chemical reduction method, display markedly enhanced electrocatalytic activity for methanol oxidation towards DMFCs applications.
 | One-step amine modification of graphene oxide to get a green trifunctional metal-free catalyst Original Research Article Applied Surface Science, Available online 14 April 2015, Pages Anwei Yang, Jingjing Li, Chen Zhang, Wenqin Zhang, Ning Ma
Graphical abstractGraphene oxide is modified by diethylenetriamine through a one-step route to prepare GO-NH(CH2)2NH(CH2)2NH2 (GO-DETA), which has primary and secondary amino groups and carboxyl groups. The obtained GO-DETA is used to catalyze Knoevenagel condensation and Michael addition in water and it shows high catalytic activity.
